Steam at 140 bar has an ethalpy of 3001.9 Kj/kg. Find the temperature, the specific volume and internal energy.
Homework Answers
first, it is necessary to decide whether the steam is wet ,dry or superheated at given conditions that are perssure=140 bar and enthalpy= 3001.9 kj/kg according to steam table.
from steam table whose pics i have
enclosed in my answer, clearly shows at 140 bar pressure , steam is
not at saturated level as at this pressure saturated vapour
enthalpy is 2638kj/kg which is less than given enthalpy that is
3001.9kj/kg.
therfore it is at superheated state so from steam table,clearly at 140 bar pressure having enthalpy 3001.9(approximately equals to 3002), steam is at - temperature 400 degree celsius
- having specific volume,v,= 0.0172 m3/kg
- having internal energy,u,= 2761 kj/kg
