A continuous cast steel slab, 1m × 1m × 0.1m at 1298 K cools in air. The initial rate of heat loss (in kW) from the top surface of slab by radiation and convection is _____ (answer up to two decimal places)
(Given (i) Ambient temperature= 298K (ii) emissivity of steel=0.8 (iii) convective heat transfer coefficient = 4.6 W m-2K-1 (iv) Stefan-Boltzmann constant (σ)= 5.7 × 108 W m-2 K-4
