Water is the working fluid in an ideal Rankine cycle. Superheated vapor enters the turbine at 8 MPa, 450 °C. The condenser pressure is 7.5 kPa. The net power output of the cycle is 100 MW.
(a) Draw and label the T-s diagram for the ideal Rankine cycle that you would use to solve this problem.
(b) Determine for the cycle the rate of heat transfer to the working fluid passing through the steam generator, in kW.
(c) Calculate the thermal efficiency.
(d) Determine the rate of heat removal at the condenser, in kW. If the cooling water enters the condenser at 15 °C and exits at 35 °C (with negligible pressure change) what would be the required mass flow rate of the condenser cooling water in kg/h?

A 782 pound 4WD vehicle is designed to clime a 16 degree ramp. What is the minimum acceptable coefficient of friction between its tires and the ramp surface?
Why does a car engine stop when we turn the key even when the vehicle is running? The engine should run on alternator in case of a petrol engine and on it's own in case of a diesel engine. Then how does it stop exactly?
Friction between the piston and cylinder wall can be neglected because the process occurs so slowly. For the air, determine the initial and final pressures in kPa and the boundary work for the process in kJ.
