Renovations After you have created volatility in the ground floor of the ditch it should be evenly filled with the ground bearing. If the bottom of the ditch, filling up to a height of cm over rocky bottom. Filler material will be sand, gravel must be non-adherent sand or gravel mixed. Channel depth should be at least cm and materials to be made into filler sand or gravel should be non-adherent sand mixed gravel.
Otherwise, the sand and so on should be utilized.

Radiation design by CGI mesh modeling. Should illustrate the point nicely! I should suggest this to the good people making Kerbal. Could be a cool part of the design experience for nuclear spacecraft. I’ve found that a smaller shadow shield diameter is possible by adding truss segments between the shadow shield and the aft end of the radiator panels. Because the truss is lighter than the shadow shield, you realize a mass savings. He is also using Blender 3D. Click for larger image, and to read William Black’s detailed analysis and work logs on the project.
Dogmatic Pyrrhonist and I both set about individually setting up a radiation simulation by CG lighting; his results are to be found at links in this thread November 6, Initially, for purposes of approximation, I used a cone, which you strip out of the scene once it has served its purpose, this is used to insure the radiators panels and everything else forward of the shadow shield are completely within the shadow region.
It is a matter of placing the cone so to intersect the aft-most edge of the radiation shadow shield, if all components forward of the shadow shield are properly placed nothing should protrude through the surface of the cone. I realized the technique can be used not only to optimize the shadow shield in terms of placement, but also in terms of diameter.
Flume Numerous types of flowmeters are available for closed-piping systems. In general, the equipment can be classified as differential pressure, positive displacement, velocity, and mass meters. Differential pressure devices also known as head meters include orifices, venturi tubes, flow tubes, flow nozzles, pitot tubes, elbow-tap meters, target meters, and variable-area meters, Fig. Positive displacement meters include piston, oval-gear, nutating-disk, and rotary-vane types.
Velocity meters consist of turbine, vortex shedding, electromagnetic, and sonic designs.
my buick lasabre will not run with the mass flow sensor hooked up. ive tried a cheap on and an oem absolutly will not run. without it hooked up it runs except when approaching 70 mph, where it bogs down and loses power no matter how much gas. the code is for the maf no matter which one is hooked up.
If more than one hook-up is shown, it means more than one test is required to check all parts of the switch. Do all tests shown for your switch. The letter next to the hook-up refers to the test procedure. Switch may be tested on or off vehicle. Slowly move throttle linkage back and forth from idle to wide open position. Page 22 Section 2 What is it? Observe all safety precautions see page ii if testing sensor on vehicle.
Slowly push sensor element back and forth from end to end. Range of TEST light movement varies with sensor type and vehicle mounting. If the Red and Black test lead hook-ups are reversed, the TEST light will move in the opposite direction during the test. This does not affect the accuracy of the test or harm the sensor. The oxygen sensor is a zirconium dioxide ceramic mounted in the tip of a threaded metal housing.

Galvanic Cells and the Nernst Equation Step 3: Measuring cell potentials In the previous step, we harnessed the energy of the chemical reaction by creating a galvanic cell to power a stopwatch. In this section we will look at how to measure the energy produced in a galvanic cell. Using this information we can understand why some of the reactions powered the stopwatch and others did not. To measure the energy produced in a galvanic cell, we will use a voltmeter, placing it in the pathway of the electrons on the wire.

This expands the range of measurements that can be performed, from the higher flow rates down to the lower end of the flow span, and ensures stable and accurate flow rate output, which is normally difficult for vortex flow meters. Steam Flow Measurement Steam has often been described as the ‘lifeblood’ of the industry. Vortex meters are known to be superior devices for steam flow measurement due to their inherent linear measurement, large turndown, low pressure drop, and high accuracy.
The multivariable vortex flow meter is ideal for high temperature, superheated, and saturated steam applications since it eliminates the need for separate components and associated installation temperature. In addition, it provides quality, dependability and high pressure ratings along with a stable and reliable flow measurement. Read the application note to learn more. Liquid Applications Liquid applications in the oil refinery industry become challenging since the process liquid is a higher viscosity at lower process temperatures.
Findail, wheres the poll option for balanced airflow? Hey, no fence riding! Actually, if I put that option up, then everyone would probably pick it. So the poll question is based on the assumption that you can never perfectly balance your airflow. With that being the case, which way should you err — positive or negative? This thread really has my noggin going now.

History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.
You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.
The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery. Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations.
They did not have the benefit of cheap, off the shelf, mass produced batteries. For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn’t until the twentieth century that new applications created the demand that made the battery a commodity item. In recent years batteries have changed out of all recognition. No longer are they simple electrochemical cells. Today the cells are components in battery systems, incorporating electronics and software, power management and control systems, monitoring and protection circuits, communications interfaces and thermal management.

Need a guide to try it out by your self? Find out here… Some background The ECM is able to do such a gigantic job by executing a software created for that purpose. This software is called and executed every time you turn the key to start your car. The software is specific for each engine and each ECM and allows to easily control the engine in a way that previous mechanical fixed systems could not.
Modern cars no longer use carburetors. The EFI system replaces the carburetor functions entirely. It does the job by sensing environment variables such as atmospheric pressure, air temperature, ignition advance angle, coolant temperature, altitude, air density and some other variables that allow such a system to precisely determine the exact amount of fuel needed to be injected to keep the engine running smoothly and in optimum conditions.
