An orbiting satellite has a mass of 5000 kg and is traveling at a constant velocity of v0. to alter its orbit, an attached rocket discharges 100 kg of gases from the reaction of solid fuel at a speed of 3000 m/s relative to the satellite in a direction opposite to v0. the fuel discharge rate is constant for 2 seconds. determine (a) the thrust exerted on the satellite, (b) the acceleration of the satellite during this 2-second period, and (c) the change of velocity of the satellite during this time period

What is the main objective of using reheat rankine cycle?

Apressure vessel with an r/t 20 cannot be treated as thin walled vessel. a)-trune b)- false

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
