A domestic pipe system is composed of different pipes with different elevations and diameters. Assuming no friction and no losses occur in our system and considering that the supply line has the pressure energy of 16 m, kinetic energy of 1 m, and potential energy of 1 m, determine which water pipe from the water supply line will have higher pressure energy: a) At the same elevation and the half diameter of pipe b) At the half elevation and the same diameter of pipe

Question
A domestic pipe system is composed of different pipes with different elevations and
diameters. Assuming no friction and no losses occur in our system and considering
that the supply line has the pressure energy of 16 m, kinetic energy of 1 m, and
potential energy of 1 m, determine which water pipe from the water supply line will
have higher pressure energy:
a) At the same elevation and the half diameter of pipe
b) At the half elevation and the same diameter of pipe
(a)
(b)

Air is drawn from ambient conditions into a long 50 mm duct by a fan. If the air
flow rate is measured at 60 litres/s, determine the entrance length before fully
developed flow is established in the pipe.
