A steam power plant operates on an ideal reheat Rankine cycle and uses water as the working substance. Steam enters the high-pressure turbine at 12.0 MPa and 500 °C where it expands to a pressure of 2.0 MPa. After which, it is reheated to 500 °C and then expands again in the low-pressure turbine to a pressure of 10 kPa. Then, it enters the condenser and leaves as saturated liquid. It is then pumped into the boiler back to a pressure of 12.0 MPa. Assuming all processes are ideal, then the thermal efficiency of the power plant is nearest to:

Part A U1 = Submit Each blade on a wind turbine is engineered to produce an effective force through its center of mass that is perpendicular to its long axis. (Figure 1) The magnitude of the force produced by each blade in a wind of speed v is F = (40.0 kg/s)v. If the center of mass of each blade is r = 10.2 m, what is U₁, the total work done by the wind turbine's blades, in a wind of speed v = 7.35 m/s after 10 revolutions?

(Figure 2) The tire's radius is R = 50.0 cm and the brake system's radius is r= 19.3 cm. A moment of M = 13.8 Nm is applied to the tire for 5 rotations before the brake system is applied. The brake system is composed of two pads…
