Water at 60F enters a 1-in.-ID tube that is used to cool a nuclear reactor. The water flow rate is 30 gal/min.

Determine the total heat transfer, the exiting water temperature, and the wall temperature at the exit of a 15-ft long

tube if the tube wall condition is one of uniform heat flux of

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
