A U-tube is made up of two capillaries of bores 1.2 m and 2.4 mm respectively. The Tube is held vertical and partially filled with liquid of surface tension 0.06 N/m and zero contact angle. If the estimated difference level in the two menisci is 1.5 mm, determine the mass density of the liquid

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
