When surrounded by air at a pressure of 1.0 * 105 N>m2 , a basketball has a radius of 0.12 m. Compare its volume at this condition with the volume that it would have if you took it 15 m below the water surface, where the pressure is 2.5 * 105 N>m2 . What assumptions did you make

How much work is done lifting a 9.10 kg box straight up onto a shelf that is 1.80 m high?

According to the tide table below what time of day will the highest tide occur?

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.
