Ye 45mm is the head loss but it's theoretical and not related to the initial equation. Would the formula be h1 - h2 = p2 - p1 / density x g ?
Thanks for your help
Trying to calculate pressure difference between sections 1 and 2.
1=32mm 2=20mm
density = 1000 kg/m^3
I have done P1-P2 = 1/2 density x (vi^2 - vj^2)
Is this right?
How do I now find head loss if difference between 1 and 2 were 45mm ?
45/density x gravity ?
Thanks,
Surely the temperature within the condenser has to be higher than the external temperature in order for the condenser to reject heat. Within the evaporator the temperature is lower to allow the heat from the warm environment (the room etc) to be absorbed. Heat will only flow from a region of...
Basically we have been set this question and there are numerous equations on the back that we have to pick from. I take it from your response I have selected the wrong equation initially. Should it be 1/2g (V22 - V1 2) ??
Hi Tim,
Thanks for getting back to me.I am trying to answer the question but think I may be going about it the wrong way.
Using the Bernoulli equation do I need to transpose to find P ?
