Q19.
An open tank contains 5.0 m of water covered with 2 m of oil (y = 8.0 kN/m'). Find the gage pressure (a)
at the interface between the liquids and (b) at the bottom of the tank.
Your answer
Q20.
The work required to compress a gas from 100kPa and 300K to 300kPa pressure is 280kJ/kg of
the gas. The compressed gas is admitted to a nozzle in which its velocity is increased to
700m/s. Find the heat required during compression if the gas enters the compressor with
negligible velocity and leaves the nozzle at 100kPa and 300K.
