How much solar energy is received by 5m^{2} in 2 hour? Given solar constant = 1.4 kW/m^{2}.
If the solar energy received in 5 minutes by 10m^{2} area is 4200 kJ, find the value of solar constant
Calculate the heat energy received by 5m^{2} area on the Earth's surface in 1 minute, assuming that 47% of the solar energy strikes the Earth's surface.
The surface area of a concentrator type solar cooker heater is 5m^{2}. It reflects 80% of the radiation incident on it. Calculate the energy concentrated by the heater in 1 hour if the solar energy were delivered to it at the rate of 0.66 kW/m^{2}.
