heat generated from oil movement

heat generated from oil movement

(OP)
I am looking for a chart or calculation for the temperature increase of oil movement (creating a heat sourse from presure oil movememnt) I want to capture the heat for other usage how much heat can I produce (degrees)(btu)

RE: heat generated from oil movement

I believe that you should be able to calculate the energy released providing you know the pressure drop and flow rate. Make sure you take head pressure into account.

pressure drop - head pressure = pressure loss due to friction

psi x gpm
HP = ---------
1714

kPa x lpm
kW = ----------
60,000

RE: heat generated from oil movement

Another way...

Delta T(Degrees C) = 5.7 x Delta P(BAR)
-----------------
100

Delta T(Degrees F) = 7 x Delta P(PSI)
-----------------
1000

Example...

A relief valve opening at 200 BAR gauge pressure and venting into an open tank at zero gauge pressure. The low pressure oil would be 11.4 degress (C) warmer than the high pressure oil.

RE: heat generated from oil movement

Another way is to figure the HP input and take that times 2,545 BTU/Hour.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
White Paper - The Other Side of Design for Assembly
Assembly level constraints need to be satisfied before the design can move downstream. This white paper will go through the various assembly level issues, which need to be tackled by various organizations on a regular basis. Know more about DFMPro, a design for assembly software. Download Now
