Of course...I really hate having to use the US system...Thanks again!

That seems reasonable. Not entirely sure what you did...but it does end in psi! Why do you cancel out gravity? Also, my thanks to you are endless. I have been canceling units for two days now.

Yeah, sigh...that's what I've been doing for two days straight. After I multiply the head loss by density and gravity I get pressure loss in lb/(in*hr^2). Which seems eerily similar to Pascals. So I convert lb to kg, into m, and hr^2 to s^2 by multiplying by 1.49569X10^-6. Then I convert Pa to...

Yes, that is in inches. I agree, that number seems reasonable. How should I convert that from inches to psi?

I will go through my steps exactly so that I can hopefully get some help. GIVEN: temp=100 F viscosity=1.202 cts mass flow=2000 lb/hr density(rho)=.0288 lb/in^3 diameter=.715 in length=204.88 in g=5003700480 in/hr^2 total K=20.41 STEPS: 1. convert viscosity to US: 1.202*5.58=6.70716 in^2/hr 2...

The pipe inside diameter is .715. For a mass flow of 2000 lb/hr I got a fluid velocity of 190909.94 in/hr. I think the problem is in how I am calculating my fluid velocity. How can I calculate the average velocity knowing only the flow, diameter, length, viscosity, and density?

Hello. I have been asked to calculate the pressure drop across our fuel system. It is a large system with many fittings and bends. My numbers don't seem to make sense to me Please help... Before I begin, I use equation dp=(K*density*MeanVelocity^2)/(2*g) to calculate pressure drop. To...

Alright that makes sense. What effect does a change in height have on pressure drop? For instance, I have a tube that is carrying a fluid and the tube starts at a pump and connects at a filter below. The tube has a large radius bend.

First, I am very confused as to the difference, if any, between head loss and pressure drop/loss. Can someone help me? Also, I know that the Darcy-Weisbach equation for head loss due to friction is hf=fL/D*V2/2g and you can plug that into get an equation for delta p that is dp=fL/D*pV2/2...
