Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450ยฐc 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.

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^โ2m on an edge at the ocean's surface, decrease by 7.5 x 10โ10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^โ2, delta v=7.5x10^โ10. at some point l needs to be cubed. why p is divided by delta v?
