A solar hot-water-heating system consists of a hot-water tank and a solar panel. The tank is well insulated and has a
time constant of 60 hr. The solar panel generates 2200 Btu/hr during the day, and the tank has a heat capacity of
3°F per thousand Btu. If the water in the tank is initially 105°F and the room temperature outside the tank is 81°F,
what will be the temperature in the tank after 10 hr of sunlight?
What is U(t), the rate of temperature change due to the solar heating panel? Select the correct choice below and,
if necessary, fill in the answer box to complete your choice.
O A. U(t)= °F/hr

Assume that the resulting internal energy leaves a person’s body by radiation and convection of dry air.
