10- Át the discharge of an air-conditioning duct, it is desirable to reduce the cross-sectional area of the duct, as shown in (Fig. P10). The cross-sectional area of the smaller duct is 0.02 m². At section 1 of the larger duct, the pressure, stagnation temperature and velocity are 150 kPa, 327 K and 71 m/s, respectively. If the flow throughout the duct is isentropic and discharge to an ambient pressure of 100 kPa, determine the mass flow rate [Answ. 6.66 kg/s]

An air pump is used to fill a rigid gas bottle with air. The pump is connected to the gas bottle via a rigid pipe. The pump consists of a piston of internal diameter d=0.08 m and a cylinder with a stroke L=0.3m. Air enters the pump through an orifice located at the bottom of the cylinder to raise the pressure in the pump to atmospheric pressure. Air, drawn into the pump through the orifice, mixes completely and adiabatically with the cylinder contents. A valve allows the bottle's refill. The valve opens when the pump pressure is equal to the gas bottle. The valve is always closed when the pump pressure is below the gas bottle pressure. Pressure drop across the valve can be neglected. The bottle, the connecting pipe and the pump are thermally insulated. Air in the pump and connecting pipe undergoes isentropic compression and expansion processes. I F-one The working fluid (air) can be considered a perfect gas with R=287 J/KgK, cp=1005 J/KgK and y=1.4. Initially the piston is located at…
