Oil (p = 888 kg/m³, µ = 0.8 kg/m.s) is to be transported in a smooth pipe having d' meter D = 5 cm and length L = 40 m. a. If the pressure at inlet was P₁ = 745 kN/m², and at exit was P₂ = 97 kr/m², calculate the flow r Q if: i. ii. iii. The pipe was horizontal The pipe was inclined upwards by 15° The pipe was inclined downwards by 15° You may assume that the flow in all three cases was laminar. Confirm, by calculating the resulting Reynolds number, that this assumption is valid for each of the three cases. b. If the flow rate in the horizontal pipe is increased such that Reynolds number Re = 105, calcula the pressure drop that would occur between the pipe's inlet and outlet. Evaluate f from the Blasius equation.

Transcribed Image Text:Oil (p = 888 kg/m³, µ = 0.8 kg/m.s) is to be transported in a smooth pipe having d' meter D = 5 cm and
length L = 40 m.
a. If the pressure at inlet was P₁ = 745 kN/m², and at exit was P₂ = 97 k' /m², calculate the flow rate
Q if:
i.
The pipe was horizontal
ii.
The pipe was inclined upwards by 15°
iii. The pipe was inclined downwards by 15°
You may assume that the flow in all three cases was laminar. Confirm, by calculating the
resulting Reynolds number, that this assumption is valid for each of the three cases.
b. If the flow rate in the horizontal pipe is increased such that Reynolds number Re = 105, calculate
the pressure drop that would occur between the pipe's inlet and outlet. Evaluate f from the
Blasius equation.
