Initially the question is worded quite loosely which is confusing (see top). For the first part of applying the first law of thermodynamics (assuming its a closed system) Q2 = U2 - U1 + 1W2 and this needs to be applied to the system eliminating parts not needed. P cannot be moved as you said
For the first law I have used Q-W = difference in energy and attempted to find the temp via finding the internal energy and enthalpy using deltau = cv x delta T and delta h = cp x delta T where I got 8520 KJ and 12063 KJ but now I am not sure how if I should integrate and remove pressure from...
Hi,
For the first law I have used Q-W = difference in energy and attempted to find the temp via finding the internal energy and enthalpy using deltau = cv x delta T and delta h = cp x delta T where I got 8520 KJ and 12063 KJ but now I am not sure how if I should integrate and remove pressure...
Hi all I am struggling with this classs example
A pump compressing hydrogen from a low pressure to a high pressure tank where the tanks pressure is constant and H2 is an ideal gas.
Hydrogen: (H2: MW = 2, Cv = 10 kJ/kgK)
Low pressure tank: (P = 4 bar, T = 30oC)
High pressure tank: (P = 100...
Hi all I am struggling with this textbook example :( I have applied the formula but the numbers I am getting are really wrong!
