A fluid flowing in a pipe has 1.05 in diameter. If the fluid has density, viscosity and
volumetric flow rate are 62.3 , 1.2 cP and 35 gpm respectively. Calculate: 3
a) The velocity.
b) Reynolds number ()

[2]- Find the following
a) Drive an expression to find a pressure of methane gas at point B b) If the temperature of methane is 100 F, Calculate pressure of
methane gas at point B.
c) Calculate pressure of oil at point C.
PA = 1, 000 psig
[3]- If the water is pumped down one well and the displaced oil which flows up through well exit (see the fig below), drive an expression to find a pressure of inlet water Pw needed to displace oil when the water/oil interfacial tension σ is applied.
