Pressure gauge on flow test pipe reading zero, why? "The pressure gauge is reading zero, except for burst pressure upon closing the inlet " Should that be "outlet"? In any case, if you close the outlet do you get the same pressure as that in the tank? (You should ) I'm an electrical engineer so this isn't my specialty, but what pressure drop are you expecting on the elbow and what would you expect on 2' of pipe (I'm thinking that all the
Question About Pumps in Series - Engineering Stack Exchange Pump2 primes Pump1 So far OK Pump1 turns on, and both for recirculation and taking some load off Pump2 Probably OK thanks to recirculation making up flow difference Pump2 turns off This is where things get a little hairy since Pump1 might actually end up driving Pump2 and Pump2 may not handle that solution is a bypass of pump2 with a
Mass balance of a recycle stream - Engineering Stack Exchange I'm a chemical engineer student and I have just started to learn about mass balance without reaction This is my problem - I want to find Out the mass composition and mass flowrate of stream Y (
How to calculate a circulation pump size? - Engineering Stack Exchange Does the 1 liter of water is replenished by a constant inflow, or the water is circulating in a closed-loop? If it is the former case, what is the flow rate of the makeup water? Your description is quite confusing, try explain better, please
How to calculate torque on gearbox? - Engineering Stack Exchange The largest torque applied to the gearbox occurs at the low-speed side In this case, this is at the load-side of the gearbox, as opposed to the motor-side So, all you need to do is compute the torque the load exerts directly to the gearbox If we know the maximum load to be lifted, and we know the radius of the winch pulley (or more accurately, the horizontal distance between the centre of
fluid mechanics - Where exactly will a hydraulic jump occur . . . Just because supercritical flow is a requirement for hydraulic jumps to occur doesn't mean that it's the fact of supercritical flow that causes the jump The Froude number simply represents a limiting condition on the flow; if the Froude number is less than 1, jumps won't occur regardless of the geometry of the channel If you read the WP article carefully, you should start to see that it's
Designing for a specific flowrate - Engineering Stack Exchange Many commercial hot water recirculation pumps will do that Just grabbed one at random - Grundfoss Alpha1 15 40 130 I couldn't fetch the page after I ran their calculator I used temp of 99C and head of 2m 100C doesn't work in their calculator Click link then click "view in product center", and fill in form ALPHA1 circulator pump - heating, cooling, hot water You also have to edit settings
