He's not an early morning person, but he does stay quite late, until about 7 or 8 in the evening, she said.
Heat (Btu/hr) = Flow Rate (GPM) x 210 x Temperature Difference (oF) Btu/hr Q = GPM x 210 x rT. Heat In Fresh Water (approx.) Heat (Btu/hr) = Flow Rate (GPM) x 500 x Temperature Difference (oF) Btu/hr Q = GPM x 500 x rT. Heat In 50% Ethylene Glycol and.
{Sigh} I hate English units. A BTU is defined as the amount of heat required to raise the temperature of 1 lb of water by 1 deg F. The basic relation is Q = mcdT Heat = mass * â¦ heat capacity * change in temperature.A gallon of water weighs about 8 lb, so you're talking about 500,000 gal * 8 lb/gal = 4 million pounds. BTU is defined as the amount of heat required to raise the temperature of 1 lb of water by 1 deg F. The basic relation is Q = mcdT Heat = mass * â¦ heat capacity * change in temperature.
