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

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal

What is the correct way to measure the overall length of a boat? measure from the tip of the bow to the highest point on the gunwale. measure from the tip of the bow in a straight line to the stern of the boat. measure from the tip of the bow in a straight line to the back seat. measure from port to starboard at the boat's widest point.
