actual exhaust velocity वाक्य
"actual exhaust velocity" हिंदी में actual exhaust velocity in a sentenceउदाहरण वाक्य
- For air-breathing jet engines, particularly turbofans, the actual exhaust velocity and the effective exhaust velocity are different by orders of magnitude.
- This allows a better match between the airspeed and the exhaust speed, which saves energy / propellant and enormously increases the effective exhaust velocity while reducing the actual exhaust velocity.
- Note that "'effective "'exhaust velocity and "'actual "'exhaust velocity can be significantly different, for example when a rocket is run within the atmosphere, atmospheric pressure on the outside of the engine causes a retarding force that reduces the specific impulse, and the effective exhaust velocity goes down, whereas the actual exhaust velocity is largely unaffected.
