## ﻿Find Amount Of Heat Required To Convert 3000 Kg Of Boiler Feedwater At 90c Related Information ## Specific Heat Calculator

Oct 21, 2016 · Determine the mass of the sample. We will assume m = 5 kg. Calculate specific heat as c = Q / (mΔT). In our example, it will be equal to c = -63,000 J / (5 kg * -3 K) = 4,200 J/(kg·K). This is the typical heat capacity of water. If you have problems with the units, feel free to use our temperature conversion or weight conversion calculators.

A large amount of water vapor or hydrogen increases the speciﬁc heat and thermal conductivity of the gas and hence the boiler duty and heat ﬂux. For example, the reformed gas in hydrogen plants has a large volume of hydrogen and water vapor, which increases the heat transfer coefﬁcient by 500–800% compared to typical ﬂue gases.
