What is the power output of the heat engine?

AI Thread Summary
The heat engine operates with a hot reservoir at 100°C and a cold reservoir at 0°C, condensing 11 kg of steam and melting 52 kg of ice over 1.3 hours. The power output can be calculated using the equation W = Qin - Qout. To determine Qin and Qout, it is essential to reference the latent heats of steam and ice, which provide the necessary heat values for the phase changes. The discussion emphasizes the importance of understanding these latent heats to solve for the power output effectively. Accurate calculations will yield the engine's efficiency and performance metrics.

Homework Statement


The hot reservoir of a heat engine is steam at 100^ C while the cold reservoir is ice at 0 C. In 1.3 hr of operation, 11 kg of steam condenses and 52 kg of ice melts.


Homework Equations


I think power output is W=Qin-Qout


The Attempt at a Solution


I believe the equation i provided is the correct one for power output but i don't know how to find Qin or Qout from the information given. So any help would be appreciated.

Look up latent heats. They tell you how much heat is required to melt/freeze or condense/evaporate a substance.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
