The flow rates in the reservoir and the slit both increase as the piston speed increases and then decay shortly after the re-entrant area.
From this we can see that, since the piston area F remains constant, the pump flow varies according to the same law as the piston speed.
The combination of a closed hood with a cooling air inlet together with a surprisingly low piston speed of 3m/sec and optimised air flow over the cylinder keeps vibration levels to a minimum and the temperature of components to a very low level.
Optimization has shown that several kN's of reacting force can be reached for a shock-absorber having dimensions similar to conventional design at a piston speed of 0.
A former editor of Car Craft and Hot Rod, and himself a racer, Baechtel sets out and explains calculations of such matters as engine displacement, compression ratio, torque and horsepower, intake and header size, injector sizing, and piston speed.
The pressure losses and their effect on efficiency and power of the engine depend on the piston speed and the speed of the engine.
A brushless servo digital drive provides a piston speed range of up to 1200 mm/min.
Unless, of course, I can come up with something as exciting and innovative as a low-cost, low-energy dehumidifier, or perhaps a controlled piston speed engine that reduces emissions of carbon dioxide, nitrous oxide and unburned hydrocarbons (absolute swines to shift, they are).
The measurement interval varies from 6 s to 60 s, depending on piston speed.
An evaluation of available materials and the desired time between overhauls determined both the piston speed (and thus the stroke) and the brake mean effective pressure.
This formula assumes that the effective pressure is 90 pounds per square inch, that the piston speed is 1000 feet per minute and the mechanical efficiency is 75 percent.
