The output specific heat is given as kJ/(kmol*K), kJ/(kg*K), kWh/(kg*K), kcal/(kg K), Btu(IT)/(mol*°R) and Btu(IT)/(lb m *°R) The calculator below can be used to calculate the liquid water specific heat at constant volume or constant pressure and given temperatures. Isobaric specific heat (C p ) for water in a constant pressure (ΔP = 0) system.I sochoric specific heat (C v ) for water in a constant-volume, (= isovolumetric or isometric ) closed system.The specific heat is given at varying temperatures (☌ and ☏) and at water saturation pressure (which for practical use, gives the same result as atmospheric pressure at temperatures < 100 ☌ (212☏)). When calculating mass and volume flow in a water heating systems at higher temperature - the specific heat should be corrected according the figures and tables below. Moist unit weight The unit weight of a soil when void spaces of the soil contain both water and air.Specific heat (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree. In soil mechanics, specific weight may refer to: Specific weight is often used as a property of soil to solve earthwork problems. Specific weight can be used as a characteristic property of a fluid. For this reason, units are expressed as force per unit volume (e.g., N/m 3 or lbf/ft 3). In fluid mechanics, specific weight represents the force exerted by gravity on a unit volume of a fluid. Pressure may also affect values, depending upon the bulk modulus of the material, but generally, at moderate pressures, has a less significant effect than the other factors. It depends on the value of the gravitational acceleration, which varies with location. ![]() Unlike density, specific weight is not a fixed property of a material. The standard gravity is acceleration due to gravity, usually given in m/s 2, and on Earth usually taken as 9.81 m/s 2. The density of the material is defined as mass per unit volume, typically measured in kg/m 3.
