Question

An electric generating plant boils water to produce high-pressure steam. The steam spins a turbine that is connected to the generator.

a. How many liters of water must be boiled to fill a 5.0 m3 boiler with 50 atm of steam at 400$°$C?

b. The steam has dropped to 2.0 atm pressure at 150$°$C as it exits the turbine. How much volume does it now occupy?

Short answer

(a) the amount of water that needs to be boiled

(b) The steam takes up a certain amount of space.

Step-by-step solution

Step:1 Given information

(a) To fill a $5.0{\mathrm{m}}^3$boiler with $50\mathrm{atm}$of steam at $400°\mathrm{C}$, how much water must be boiled

Water boiled

(a).the volume of water that needs to be boiled

Given information

As it exits the turbine, the steam has plummeted to $2.0atm$ pressure and$150°\mathrm{C}$

Step: 4 Steam Occupied

The steam takes up a certain amount of space.
