A simple solar collector in Figure Q1 is built by placing a 5 cm diameter clear plastic tube around a garden hose whose outer diameter is 1.6 cm. The hose is painted black to maximize solar absorption, and some plastic rings are used to keep the spacing between the hose and the clear plastic cover constant. During a clear day, the temperature of the hose is measured to be 65 °C, while the ambient air temperature is 26 °C. Determine the clear plastic tube temperature and the rate of heat loss from the water in the hose per meter of its length by natural convection.

A simple solar collector in Figure Q1 is built by placing a 5 cm diameter clear plastic tube around a
garden hose whose outer diameter is 1.6 cm. The hose is painted black to maximize solar absorption,
and some plastic rings are used to keep the spacing between the hose and the clear plastic cover
constant. During a clear day, the temperature of the hose is measured to be 65 °C, while the ambient
air temperature is 26 °C. Determine the clear plastic tube temperature and the rate of heat loss from the
water in the hose per meter of its length by natural convection.
