Consider a flat-plate solar collector placed horizontally on the flat roof of a house. The collector is 5 ft wide and 15 ft long, and the average temperature of the exposed surface of the collector is 100°F. The emissivity of the exposed surface of the collector is 0.9. Determine the rate of heat loss from the collector by convection and radiation during a calm day when the ambient air temperature is 70°F and the effective sky temperature for radiation exchange is 50°F. Take the convection heat transfer coefficient on the exposed surface to be 2.5 Btu/h · ft2 · °F.
two point charges -2q and 3q are on the x-axis -2q at the origin and 3q at x d. choose the potential to equal zero at
A penny of mass 3.1g rests on a small 20g block supported by a spinning disk. The coefficients of friction between the block and disk are 0.75 (static) and 0.64 (kinetic).
