An airflow at Mach 0.6 passes through a channel with a cross-sectional area of 50 cm?. The static pressure in the airstream is 50 kPa; the static temperature is 298 K. (a) Calculate the mass-flow rate through the channel. (b) What percent of reduction in area would be necessary to increase the flow Mach number to 0.8? to 1.0? (c) What would happen if the area were reduced more than necessary to reach Mach 1?

Please answer and show working out please and label each part

Water is the working fluid in a Rankine cycle. Steam exits the steam generator at 1500 lbf/in.? and 1100°F. Due to heat transfer and frictional effects in the line connecting the steam generator and turbine, the pressure and temperature at the turbine inlet are reduced to 1400 Ibf/in.? and 1000°F, respectively. Both the turbine and pump have isentropic efficiencies of 85%. Pressure at the condenser inlet is 2 Ibf/ in.?, but due to frictional effects the condensate exits the condenser at a pressure of 1.5 lbf/in.? and a temperature of 110°F. The condensate is pumped to 1600 lbf/in.² before entering the steam generator. The net power output of the cycle is 5.5 x 10S Btu/h. Cooling water experiences a temperature increase from 60°F to 76°F, with negligible pressure drop, as it passes through the condenser. Determine for the cycle: (a) the mass flow rate of steam, in Ib/h. (b) the rate of heat transfer, in Btu/h, to the working fluid passing through the steam generator. (c) the percent…
