Net solar radiation of 1360 W m⁻² is incident on the surface of a still lake having mixed layer depth of 20 m. Find the change in temperature (in SI units) of the mixed layer of the lake for a day length of 8 hours. (Rounded off to 2 decimal places)

Assume that there is no variation in solar radiation in a day and all radiation incident on the surface is absorbed uniformly throughout the mixed layer (Density of lake water is 1025 kg m⁻³ and Specific heat capacity (Cₚ) of lake water is 3850 J kg⁻¹ K⁻¹).

A homogeneous, incompressible, steady ocean of mixed layer depth of 20 m has a velocity gradient −5 × 10⁻⁸ s⁻¹ and −8.3 × 10⁻⁸ s⁻¹ along zonal and meridional directions, respectively. The vertical mass flux (in kg s⁻¹) at the base of the mixed layer of 100 km × 100 km area is __________ × 10⁶ kg s⁻¹ (Density of sea water is 1025 kg m⁻³). (Rounded off to 1 decimal place)
