1. The problem statement, all variables and given/known data
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?

2. Relevant equations

What equations would I need to solve the problem?

3. The attempt at a solution
My book isn't very descriptive and its the first time in 5 years im doing physics, long distance learning as well.

I just need help in the right direction 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?
