PROBLEM:
A Venturimeter (Cd = 0.68) and Pipe orifice (Cd = 0.64) are attached one at a time to a 200mm diameter pipe. The throat and the orifice diameters are taken to be 0.25D. If the manometer readings at the pipe and the throat/orifice are taken to be 2.7m and 0.32m respectively:
Determine the flow for venturimeter
Determine the flow for the Pipe orifice
.Determine the height of water if a pitot tube was inserted instead
1 - If the pipeline is now specified to be of Schedule 40 with a nominal diameter of 6 in., and the available pressure at the pump exit is P2 = 132.7 psig, what flow rate Q (gpm) can be expected?
Answer the following additional questions:
2 -If the combination of pump and motor is 80% efficient, how much electrical power (kW) is needed to drive the pump?
3 -, in order to avoid vapour lock, the pressure in the pipeline must always be above the vapor pressure of the crude oil, what is the maximum permissible elevation of point 3 relative to point 4?
4 -If the flow in the pipeline were at the upper limit of being laminar, what pump exit pressure would then be needed? (Answer this part without using the friction factor plot.
1. How does the manometer reading of the Orifice Meter apparatus affect its discharge? If the flowrate passing through the apparatus is increased, what will happen to the corresponding theoretical discharge?
