The GPM is gallons per minute and TR is the ton of refrigeration. The GMP can be calculated from the TR by using the formula BTUH divided by 500 multiplied by Delta T.
BHP = Flow(GPM) X TDH(FT) x SG /3960xEFFICIENCY(%)Example: BHP = (100 GPM) x (95 Ft) x (1.0) / 3960 x .6BHP = 4.0
how to calculate the vapour absorption mechine efficiency and per TR steam consumption
gallon per minute (gpm).
Under 400 GPM at best (without friction)
First you need the size of the pipe and the volume of water supply. Pressure will vary during usage. Standard well system operates between 20-40 psi and city systems operate from 50-70 psi.
Tr=p.q
52 gpm
BHP = Flow(GPM) X TDH(FT) x SG /3960xEFFICIENCY(%)Example: BHP = (100 GPM) x (95 Ft) x (1.0) / 3960 x .6BHP = 4.0

gallon per minute (gpm).
not sure if that's even English.
Take the gpm of the recirculating pump and multiply by 10/2.4 equal system volume. This is used to estimate expansion tanks. It good plus or minus 10% depending on new additions
Kw x 3412 / 10000 = gpm I think
Before you can calculate the flow, you must also have the pipe size and its coefficient of friction.
The easiest way would be to capture the sprinkler water and fill a 5gallon bucket and time your self. When the buckets full then divide the time it took by 5 and you have your GPM.
To calculate the horse power of a compressor one would need to use the following calculation. Pump ratio x GPM @ 100 psi = CFM. For a gas compressor divide CFM by 2 and for an electric compressor, divide CFM by 4. GPM is gallons per minute and CFM is air consumption in cubic feet per minute.
It doesn't make any difference how many sides of the pool are negative edge, only the total number of linear feet of negative edge and how level you can make the edge. The longer the edge the more important it is that it be level, because even small amounts of out of level require huge flow rates to compensate for. Approximate GPM required per linear foot for various water depths: 1/8" - 5 gpm ¼" - 10 gpm ½" - 17 gpm ¾" - 28 gpm 1" - 40 gpm 1.5" - 70 gpm 2" - 105 gpm As a minimum 5x35=175 GPM
