Calculate the heat energy received by 5 ...

Calculate the heat energy received by `5 m^2` area on the Earth's surface in `1` minute, assuming that `47 %` of the solar energy strikes the Earth's surface.

Text Solution

Verified by Experts

The correct Answer is:
`197.4 kJ`
Heat energy received = 47 % of solar constant `xx` area `xx` time`
=`(47//100)(1.4 kW//m^2)(5 m^2)(1 xx 60 s)`
=`197.4 kJ`.
