In an ideal rankine cycle, saturated vapor enters the steam turbine at 20 bar and leaves it at 0.08 bar. it then enters the condenser, where it is condensed to saturated liquid water at 0.08 bar. determine (a) net work per kg of steam flowing, (b) the thermal efficiency of the cycle, and (c) compare the thermal efficiency of the carnot cycle.

A2000 kg car is rounding a curve of radius 200 m on a level road. the maximum frictional force the road can exert on the tires of the car is 4000 n. what is the highest speed at which the car can round the curve?

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.

1kg of water needs to recieve 4200j of energy to go from 90 degrees to 91 degrees. what is the specific heat capacity of water? what are the units?
