The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown above. Determine the gage pressure of air in the tank.
=0.2 m, =0.3m, and =0.46m.
Take the densities to be:
A sump pump is draining a flooded basement at the rate of 0.750 L/sec with an output pressure of . The water enters a hose with 3 cm inside diameter and rises 2.50 m above the pump. What is the pressure at this point?
A regenerative gas turbine power plant isshown in Fig. P1. Air enters the compressor at 1bar, 27ºC with a mass flow rate of 0.562 kg/s andis compressed to 4 bar. The isentropic efficiency ofthe compressor is 80%, and the regeneratoreffectiveness is 90%. All the power developed bythe high-pressure turbine is used to run thecompressor. The low-pressure turbine provides thenet power output. Each turbine has an isentropicefficiency of 87% and the temperature at the inletto the high-pressure turbine is 1200 K. Sketch thecorresponding T – s diagram and determine: (a) The net power output, in kW. (b) The thermalefficiency. (c) The temperature of the air at states2, 3, 5, 6, and 7, in K.
