To determine the enthalpy of water at given pressure and temperature, we first need to know the temperature of the water. Unfortunately, the pressure alone is not sufficient to determine the enthalpy. If you have additional information about the state of the water (such as temperature or if it's in a specific state like saturated liquid or vapor), please share it so that we can provide a more accurate answer.
In general, to determine the enthalpy of a substance, you'll need to refer to its specific properties - typically found in steam tables or software that provides thermodynamic properties of substances. From there, you can use the mass of water (5.0 kg) to calculate the total enthalpy of the water.
Determine the enthalpy of 5.0 kg of water at 850 kPa.
thankyou very much!
