amazing explanation really less boring

[@MukeshKumar-xi8ic]

Thanks in advance 👍

TWO CORRECTIONS: 1) at 6:42 The change in energy is the final energy, E2, MINUS the initial energy, E1. The equation in terms of E1 and E2 is incorrect, but the final value is correct: 3100 kJ/kg. 2) at 7:48 we look for a specific ENTHALPY value of 3100 kJ/kg (h column, not u). The correct P value should be 29.0 MPa, after interpolating.

Can you do an example of a balloon? or when reference states are being used
also at around 1:11 in the video. What happend with the mass in the left hand side? (d(mU)/dt). If m is dropped in the left hand side does that affect the mihi term?
btw great series

[@MukeshKumar-xi8ic]

pls add some difficult conceptual problems

[@simondemarque2826]

it is not a correct transient computation : to do it correctly (p,t,h,m) with time, you have to account of the flowrate through the nozzle, probably choked at the beginning, then the asymptotic behavior to nil of the flowrate into the insulated vessel
