Web2 okt. 2024 · This is calculated with the formula n = m/M where “M” is the molar mass that is provided (or derived). For example, the molar mass of water is about 18 g/mol, so if you have 500 grams of water you actually have 27.7 moles of water. Now to determine the moles to molecules, you multiply 27.7 by the Avogadro’s number which is 6.02*10 23. WebThe BTU is defined as the quantity of heat required to raise the temperature of one pound of water 1°F. The equation for heat transfer to a liquid is as follows: Q=W (T2-T1)Cp Q =Heat transfer per unit time (BTU/hr) W =Mass flow rate (lb/hr) T2 =Outlet temperature (°F) T1 = Inlet temperature (°F) Cp =Specific heat capacity (1.0 BTU/lb for water)
