Question 39
CHNAT2 marksNeeds review
Consider a vessel containing steam at 180 °C. The initial steam quality is 0.5 and the initial volume of the vessel is 1 m³. The vessel loses heat at a constant rate
under isobaric conditions so that the quality of steam reduces to 0.1 after 10 hours. The thermodynamic properties of water at 180 °C are (subscript
: vapor phase; subscript
: liquid phase):
specific volume:
m³/kg,
m³/kg;
specific internal energy:
kJ/kg,
kJ/kg;
specific enthalpy:
kJ/kg,
kJ/kg.
The rate of heat loss
(in kJ/hour) is __________ (rounded off to the nearest integer).Log in to check the answer
