Question:
In Problem 14.10, if the sun's rays are at 45° from the vertical, what is the greenhouse temperature?
Prob. 14.10
A greenhouse 20 m long and 15 m wide has a nearly flat roof 3 m above the floor level. When the sun is directly overhead the solar flux is 1,000 W/m2. If the glass roof has an emissivity of 0.9 and the convective losses are 0.8 times the radiation losses, what is the temperature in the greenhouse?
