Question

Saturated water vapor undergoes a throttling process from 1bar to a 0.35bar. What is the change in temperature for this process? O -4.2C O -11.3C CA-17.7C O No change in temperature for a throttling process

Answer 1

Answer:

-25.63°C.

Explanation:

We know that throttling is a constant enthalpy process

      $h_1=h_2$

From steal table

We know that if we know only one property in side the dome then we will find the other property by using steam property table.

  Temperature at saturation pressure 1 bar is 99.63°C and  Temperature at saturation pressure 0.35 bar is about 74°C .

So from above we can say that change in temperature is -25.63°C.

But there is no any option for that .
