Figuring Out Heat Transfer & Entropy of Steam at 10 MPa

AI Thread Summary
To determine the entropy change and heat transfer for water transitioning from liquid to steam at 10 MPa, steam tables are essential for obtaining the specific entropy values (sfg) and heat transfer per unit mass. The problem allows for assumptions regarding the initial temperature, which can simplify calculations. The focus should be on the vaporization process, utilizing the properties listed in the steam tables. This approach will yield the necessary values for entropy and heat transfer. Accurate application of steam tables is crucial for solving this thermodynamic problem effectively.

Hello everybody, would somebody please put me on the right track to answering this question?

'Consider water undergoes a heat transfer
at constant pressure of 10 MPa and
changes from liquid to steam. Find the
entropy of the system (sfg) as well as the
heat transfer per unit mass in this
process?'

Is this just looking at steam tables and working per unit mass?

I'd appreciate any help
Thanks

The problem does not specify initial temperature.
If you are free to assume, you could use steam tables per unit mass for the vaporization process only.

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
