AI Thread Summary
To solve the steam-related problems, the use of steam tables is essential for determining properties like boiling point, pressure, enthalpy of evaporation, and total enthalpy. Key equations include those for calculating enthalpy based on pressure and temperature, as well as the formula for total enthalpy considering the dryness factor. The discussion highlights the need for clarity on how to apply these equations effectively with steam tables. Users emphasize the importance of understanding the relationship between pressure, temperature, and enthalpy in steam calculations. Proper guidance on utilizing steam tables and relevant equations is crucial for successfully addressing the homework questions.

Homework Statement


Determine by using steamtables for 2kg of steam
- Boiling point if pressure is 5MPa
- pressure if the boiling point is 195°C
- enthalpy of evaporation at pressure 2800kPa
- total elathapy in MJ required to produce 2kg of wet steam with dryness factor of 0.7 at a pressure of 4MPa

What equations would I need to solve the problem?

The Attempt at a Solution


My book isn't very descriptive and its the first time in 5 years I am doing physics, long distance learning as well.

I just need help in the right direction to solve the problem

What equations would I need to solve the problem?

Doesn't the problem ask you to use the steam tables?
Or is an answer to that question part of the problem also?
 
Yes it does ask to use the steam tables. I am just more lost as to use which equations with the steam tables to help with my problem
 

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...
