If a 6-m cylindrical bar has a constant density of p= 5 g/cm for its left half and a constant density p = 6 g/cm for its right half, what is its mass?

Heena wants to measure the volume of a ball that is 24 cm across. how should she set up her equation?

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.
