Problem 36
1. The maximum heat transfer rate from the left end.
2. The temperature at the center of the rod at t = 1000 s.
3. The time needed for the center of the rod to reach 10?C.
An Incompressible fluid flows through a 10-in diameter horizontal constant area pipe. At one section the pressure is 150 psia and 1000 ft downstream the pressure has dropped to 100 psia.Find the total frictional force exerted on the fluid by the pipe
Air exerts a pressure of 900KPa within a 0.45 cubic meter container of fixed volume. It is cooled such that the pressure falls to 3.25bar. The temperature of the air is then measured and was found to be 285C. Determine the mass of the air, the initia..
