A manometer is used to measure the air pressure in a tank. The fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 28 in. If the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the manometer arm with the
(a) Higher and
(b) Lower fluid level being attached to the tank.
Air flows at the rate of 1kg/s through a convergent-divergent nozzle. The entrance area is 2x10^-3 m^2 and the inlet temperature and pressure are 438 K and 580 kPa. If the exit pressure is 140 kPa and the expansion is isentropic, find;
