Hi there, I'm having a problem behind the theory of bernoulli's theorem. Can it be applied in an application where water flows from a pump into a pipe with x diameter and out of a nozzle with y diameter to atmosphere. There is a pressure gauge on said pipe. There is a nozzle screwed into this...
Here is the simple diagram. So we have a pressure reading at the gauge, which is the reading for the larger pipe in which the nozzle screws into. I'm trying to calculate a coefficient of discharge, so can it be said that our pressure at the nozzle will be atmospheric pressure as it is...
I'm testing various nozzles with orifice sizes from 5mm to 40mm. The feed water comes from a hopper that is open to atmosphere into a pump. The pump has a flowmeter at the outlet. Then a pipe feeds the pumped water to the nozzle rig. The nozzle is spraying down onto screen filters. In terms of...
I work at a company that manufactures TPU screen filters for the mining industry. I've got a test to do to inspect whether the qaulity of the TPU is affected by time in the heated barrel of the injection moulding machine. The TPU material sits in the barrel due to tea and lunch breaks (15 - 30...
Homework Statement
A beam carries a uniformly distributed load, including its own weight, of 8 kN/m over its full length of 6 m. A point load of 300 kN is placed 2 metres from the one end of the beam which is simply supported.
Calculate the maximum moment of resistance for the beam if it...
Homework Statement
A Pelton wheel is driven by five identical jets. The runner has a diameter of 3,8 m, fixed in a horizontal position. The head from reservoir level to nozzles is 350 m and the efficiency of power transmission through the pipeline and nozzles is 90%. The relative velocity...
Homework Statement
The pump characteristic curve of a centrifugal pump can be plotted from the following details:
(See attachment)
The pump delivers 90 L/s when pumping against a static head of 12 m. Plot the pump characteristic curve from the details given and calculate:
1. The...
Its starting make sense now, I was just struggling with where the bottom datum should be but I can see it has nothing to do with flow rate or its direction.
Thank you so much for your time.
