A US gallon of water is about 8.4 lb, so 30,000 galls is 252,000 lb. One BTU is the heat to raise one pound of water by one degF, so BTU's in your example are 252,000 x 15 = 3,780,000 BTU.

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 does temperature affect mach number?
Mach no. is dependant on ambient air temp which is associated with a given altitude. As one ascends the temp drops so does the mach no. Eg. In a standard atmosphere (ISA - international std atmosphere) sea level temp is 15 degrees C or 59 degrees F. Temp decreases at 2 degrees celcius per 1000' therefore for example, in a standard atmosphere the temp at say 30000' would be: 15C at 0' -45C at 30000' Plug that into the equation to find the Local Speed of Sound (LSS) which is: LSS = 38.945 (square root of)/ Outside air temp + Absolute temp being 273A or 273K LSS = 38.945 x 228 LSS = 588 kts at 30000' So if one is doing 480knots at 30000' on a standard, day they are doing 480/588 = Mach0.82
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.
What is 29 percent of 30000?
29% of 30000 = 29% * 30000 = 0.29 * 30000 = 8700
What is 2 percent of 30000?
2% of 30000 = 2% * 30000 = 0.02 * 30000 = 600
What is 7 percent of 30000?
7 % of 30000 = 7/100 * 30000 = 0.07 * 30000 = 2100
How much would 30 percent of 30000 be?
30% of 30000= 30% * 30000= 0.30 * 30000= 9000
