How to calculate radiant energy

WebRadiant energy from the sun that falls on the oceans is absorbed in the “mixed-layer” of seawater, 50–100 m thick, at the surface, forming a reservoir of warm water near the … WebYou can use the Stefan-Boltzmann equation to calculate the rate at which it is radiating energy. If a hot object (temperature = T) is radiating energy to its cooler surroundings at temperature T s, the net radiation loss rate takes the form shown in Equation 2: Equation 2: P = σ A (T 4 - T s4) P is power (energy per unit time), in watts (W).
