Question

3–34 The average atmospheric pressure in Denver (elevation = 1610 m) is 83.4 kPa. Determine the temperature at which water in an uncovered pan boils in Denver. Answer: 94.6°C

Answer 1

T = 94.59 degree C

Explanation:

Given data:

P= 83.4 kPa

`P= 83.4 * 10^3 Pa (1 bar)/(10^5 Pa)`

P = 0.834 bar

for Saturated table

P = 0.8 bar T = 93.50 degree C

P = 0.9 bar T = 96.71 degree C

from interpolation method

`(0.834 - 0.8)/(0.9 - 0.8) = (z)/(96.71 - 93.5)`

z = 1.0914

T = 93.5 + z = 94.59 degree C
