Why was Cassini launched toward Venus if it is going to explore Saturn?
The orbit of Venus is between Earth and Saturn
Venus is needed to reflect the radio signals to the probe
The gravity of Venus will boost the speed of the space probe

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
