Water at 10 c enter a 2.54 cm i. d. pipe at a rate of 1.26 l/s. the pipe is 3.05 m long. if the wall temperature is held constant, at 99 c, and the water outlet temperature is 41
c. what is nusselt number for the flow? what nusselt number would you predict on the basis of the colburn analogy?

Abird sitting high in a tree is an example of what type of wnergy

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

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.
