A satellite rotates around the globe at 16,000 km/h. To reenter into the atmosphere, the speed is reduced by 1000 km/h by firing a small rocket in the direction opposite that of the satellite's motion.
(a) What are the velocity vectors of the satellite before and immediately after firing the rocket.
(b) Find the scaling factor of the original velocity vector required to get the satellite to its new speed.
a heat-engine of 32 thermal efficiency is used to drive a refrigerator having coefficient of performance of 5.
in moles of an ideal gas a and 1-nmoles of an ideal gas b each at 1 atm are mixed at total constant pressure. what
Also, compare with the efficiency of an Otto cycle operating with the same maximum pressure.
A hydraulic motor with 85% total efficiency drives a 5 kW application. If the system power supply provides fluid at a rate of 3.155×10-4m3/s, what pressure is required to satisfy the application power requirement?
