Question

For the pipeline described in the previous exercise, assume that the oil is to be heated to $100^{\circ} \mathrm{C}$ to decrease its viscosity.

a. How does this affect the pump power requirement? b. At what distance apart could the pumps be placed with the same pressure drop as that from the previous exercise?

Step 1

1 of 14**Given:**

$T=100 \ ^\circ \text{C}$

**From problem 8.39:**

DN 150 Schedule 80 steeel pipe $Q=1200 \ \frac{\text{L}}{\text{min}}=2 \times 10^{-2} \ \frac{\text{m}^3}{\text{s}}$ $L=3.2 \ \text{km}$ $sg=0.93$

How does decreasing the viscosity of the crude oil affect the pump power requirement and at what distance apart could the pumps be placed with the same pressure drop as that from Problem 8.39?
