The velocity profile in fully developed laminar flow in a circular pipe of inner radius r = 7 cm, in m/s, is given by u(r) = 4 (1 − r2r2). determine the average and maximum velocities in the pipe and the volume flow rate. (round the final answers of the velocities to two decimal places and the final answer of the volume flow rate to five decimal places.)

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
