Enthalpy in english units
WebIf you know that you need a temperature of 307 degrees F, the table tells you that you need to pressurize the system to 60 psig. If you have a 15-psi steam supply, the tables tell you that you have 945 Btu/lb. of heat energy available to do work. Properties of Saturated Steam WebMay 22, 2024 · The specific entropy (s) of a substance is its entropy per unit mass. It equals to the total entropy (S) divided by the total mass (m). Entropy quantifies the energy of a substance that is no longer available to perform useful work. Because entropy tells so much about the usefulness of an amount of heat transferred in performing work, the steam ...
