Solve the folloiwng problem:
Q: An engine oil cooler consists of a bundle of 25 smooth tubes, each of length L = 2.5 m and diameter D = 10 mm.
(a) If oil at 300 K and a total flow rate of 24 kg/s is in fully developed flow through the tubes, what is the pressure drop and the pump power requirement?
(b) Compute and plot the pressure drop and pump power requirement as a function of flow rate for 10 < m="">< 30="" kg/s.="">
