Hi Everyone,
For a test setup, I need to quickly cool JP-8 in a heat exchanger. Approximate Specifications are as follows:
Fluid: JP-8
Flowrate: 25.7 L/min (=6.8 GPM, 46 lb/min)
Inlet Temp of JP-8: 17.8°C (=64°F)
Outlet Temp of JP-8: 4.4°C (40°F)
Heat Transfer: 9 kW
I have calculated that I...

Greetings All,
I need to find a low flow rate/low pressure seawater pump that can be used at a depth of 1500ft (approx fluid pressure = 750 psi). The flow rate for the pump needs to be approx. 1.35 - 1.5 Liters/min at an output pressure of approx. 25 psi (the output pressure is estimated and...
Hi All,
Does anyone know where I could find/purchase some 16"-18" aluminum piping, scedule 40 (preferably T6061 grade, but I can entertain other alloys. Minimum yield at scedule 40 needs to be a 30 ksi)? I don't need a lot of it (two seperate 6' long sections I think will do me fine). It is for...
Hi All,
I need help in finding a seawater seal. I have a unique application where I have two filtered (to 10 microns) seawater filled chambers. A shaft turning at 3000 RPM runs between the two chambers. Chamber #1 will vary in pressure from ambient to 750 psi. Chamber #2 will have a pressure...
