2. (50 pts.) Consider a steady-state, steady-flow, regenerative power cycle with one closed feedwater heater. The mass flow rate of water going through the steam generator is 8 kg/s. The figure and table below provide some of the data needed for solving this problem, eg. you do not need to look up enthalpies in the tables. Calculate (a) The extracted flow fraction "a (b) The total turbine power (kW) (c) The total pump power (kW) (d) The boiler heat transfer...

A reheat power plant operates between the pressures of 10 MPa and 5 kPa. Steam enters the high and low pressure turbines at 400 °C. If the steam leaves the high pressure turbine at 4 MPa and steam is at saturated vapour state at the end of both turbines, total specific power output of this power plant is; A heat pump is absorbing heat from the cold outdoors at 5°C and supplying heat to a house at 25°C at a...

3. Power transmission is an important engineering application and relies on the integrity of the shaft designs. Assume a solid, circular steel shaft with a uniform diameter d 50 mm and a total length I3 m. At its midpoint, a belt passes over a pulley and delivers 50 kW power to the shaft. This power is used to drive two machines at either end of the shaft. Machine 1 consumes P1 20 kW and machine 2 uses P230 KW. The...

5. (10 points) As the price of gasoline goes up, people are willing to drive farther to fill their tank in order to save money. Assume you had been buying gasoline for $2.40 per gallon and that it went up to $2.83 per gallon at the station where you usually go. If you drive an F-150 pickup that gets 25 miles per gallon, what is the round-trip distance you can drive to break even if it will take 16 gallons...
