After a brief hospital stay, Hawking told her that he spent the time thinking about black holes. Hawking typically comes into the office after a big breakfast and reading the news, Croasdell said. 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.
A Btu (British Thermal Unit) is the amount of energy required to raise the temperature of one pound of water one degree Fahrenheit. Table 1 shows the Btu value for various energies. To compare the values on a propane equivalent we first convert the values to a MMBtu (1 million Btuâs). You take the energyâs price and divide it by its MMBtuâs. Natural gas is priced on a MMBtu basis. We then multiply the amount of propane Btu content per MMBtu (.0915) to get the propane equivalent value.
