5 Kg of water is pumped to a height of 5 m, the enthalpy is changed by 10 J/Kg, and work done by the motor is 100 J/Kg, assuming system is insulated what is the change in internal energy of water?
(a) 50 J
(b) 100 J
(c) 150 J
(d) 200 J
I got this question in homework.
The doubt is from Application of the Energy Balance to Open Systems in division Application of Energy Balances in the Absence of Chemical Reactions and Energy Balances: How to Account for Chemical Reaction of Basic Chemical Engineering
