You Are Designing A Long Building Shaped Like A Half Cylinder Similar To A Quonset Hut For Growing Crops Indoors The 1 (25.8 KiB) Viewed 35 times

You are designing a long building shaped like a half-cylinder (similar to a Quonset hut) for growing crops indoors. The roof is uniformly covered with lights so that the roof's radiosity is 550 W/m² of energy. The floor is completely blanketed in soil. The width of the building is 10 m and the dimension into the page is, by comparison, very long. The floor under the soil is well-insulated, preventing any energy loss. The building ventilation system keeps the air temperature at 24 C and the air motion produces a heat transfer coefficient with the soil of 11 W/m²/°C. The roof is opaque and has negligible reflection. The soil has an absorbtivity of 0.9 and an emissivity of 0.8. 1. How much radiant energy, in Watts per meter into the page, strikes the floor? 2. What is the soil temperature in degrees C? 10 m
