For a shell-and-tube heat exchanger in which the flow is turbulent in both the shell and tube sides, how does the film heat transfer coefficient change with a 50% increase in the mass flow rate for the (a) shell side, (b) tube side

Fluids at rest possess no flow energy. a)- true b)- false

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

A)-in the process of engineering design, explain the contribution of material selection. b)- explain the procedure of synthesis as is employed in engineering design. c)- is there any relationship between ergonomics and engineering design? explain. d)- safety consideration in engineering design includes human, product and the enviroment . explain how safety will be incorporated into the design?
