8.1 water is the working fluid in an ideal rankine cycle. the condenser pressure is 8 kpa, and saturated vapor enters the turbine at 11 mpa. determine the heat transfer in kj per kg of steam flowing, for the working fluid passing through the boiler and condenser and calculate the thermal efficiency.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
