Jan 28, 2017 · Total = 92 L/person/day. Let us take 100 L/person/day for this calculation. For 50 person, the total is = 5000 L/day or 0.92 USgpm. Peak demand is typically 5-10 L/person/h. So we take 10 L/person/h (total = 500 L/h or 2 USgpm) Potable water demand must consider peak demand = 20 + 3 + 2.2 = 25.2 USgpm. ### Pool Volume Calculator | Pentair

Nov 02, 2017 · hg = enthalpy steam (Btu/lb) hf = enthalpy condensate (Btu/lb) m = steam evaporated (lb/h) Calculate the boiler capacity for example: Boiler capacity = Burner capacity * efficiency. Example: efficiency = 95% & Burner capacity =11,110 kW. boiler capacity =11,110 kW * 0.95. ~=10,500 kW. ### Swimming Pool Water Heaters Part 1: Calculating Load

Mar 21, 2016 · 13,500 X 5 X (80-75) is about 330,000 BTUH. The pick-up, or cold start load, takes the total volume of 94,136 cubic feet of water from 40°F to 80°F in 48 hours. 94,136 X 62.3 X (80-45)/48 is about 4,300,000 BTUH. I know I can do this with a 4 million BTUH water heater. You may ask how. ### Heat Pump Calculator | Pool and Spa Calculators | Pool

The BTU/hour to Boiler Horsepower calculator is used to help size both steam and hot water boilers. This calculation translates the heat transfer input requirement to BHP. To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb, or latent energy. For this calculation, you will enter the BTU/hr of your ### Sizing Swimming Pool Heaters - Engineering ToolBox

Other factors of the pool that may impact heating performance include design and configuration, volume/size, orientation, R-value of construction materials, plumbing length/materials, operating conditions and more.
