The pressure-enthalpy diagram (log ph diagram) The thermodynamic properties of a refrigerant are often represented in a pressure-enthalpy diagram. The graph needs to be customized as shown in the pic. 1) consists of a pressure, and enthalpy axis, and includes lines of constant entropy, constant volume and constant temperatures. The unit is a 400-ton unit, to find the mass flow of refrigerant multiply 400 X 200 Btu/minute/per ton, and divide by the enthalpy difference between point 1, and point 12, or, 163 – 73 = 90 Btu The following thermodynamic properties are calculated: density water, dynamic viscosity water, kinematic viscosity water, specific inner energy water, specific enthalpy water, specific entropy water, specific isobar heat capacity cp water, specific isochor heat capacity cv water, thermic conductivity water, speed of sound water.
