Howdy,
I am working on a project for a fast food restaurant and was wondering if anyone here could point me to important chapters in the ASHRAE handbook that might be able to provide me with guidance.
The specific system I am going to be working on is the hot water delivery and want to read...
I guess the issue stems from when sizing a pump you take the largest pressure drop in the parallel components and that is the head that the pump must over come regardless of what else is in the system.
consider two situations:
1.) All // runs have the same flow and known pressure drop. The combined pressure drop (for sizing purposes) is the pressure drop across one collector.
2.) The // runs are of unequal length and therefore have uneven pressure drop. To size the pump, the max head...
Hopefully you guys can help me here. When calculating the head to size a pump how to you combine the pressure drop through a parallel bank. Say you have 3gpm through 6ft of 3/4in pipe. I know you cannot just add them up but I have been told that you can just size the pump based on one of the...
Can someone out there help me gather a list of companies that produce hub motors. I am working on a project on a Formula SAE racecar and we want to utilize hub motors in the design. We are currently in touch with PML over in England but are trying to search for other options.
