What is 20 percent in a 55 gallon tank?
How much water do you take out of a 55 down to be 20%
How many BTU needed to operate 30000 gallon pool at 80 degrees?
It takes 8.34 BTU to heat 1 gallon of water 1 degree F. Take 8.34 BTU times number of gallons to determine energy needed to raise pool 1 degree F. Then multiply by how many degrees you need to raise the temperate of the current pool temperature to the desired temperature. Example: 8.34 * 30,000 gal = 250,200 BTU need to raise temperature 1 degree F Next multiple by the number of degrees to warm, say the pool is 55 F. 80F - 55F = 25F. 250,200 BTU * 25 F = 6.255 million BTUs to heat the pool to 80 F. This does not take into account the loss of energy to the surroundings but gives you a starting point to determine the energy needed to heat a mass of water.
How long will it take to raise a pool temperature by 10 degrees with a 250000 BTU propane heater and 30000 gallons of water?
probably more than one second
How much gas does it take to drive 750 miles if i get 25 miles to the gallon?
Seriously? 750 divided by 25 = 30. 30 gallons of gas.
