c .... work is force x distance as a definition
Answer:
55000 W/m²
Explanation:
Parameters given:
Surface temperature, T = 1000°C
Hear transfer coefficient, h = 55 W/m²C
Convection heat transfer coefficient is given as:
h = Heat flux/Temperature
Hence, Heat Flux, q, is given as:
q = h * T
q = 55 * 1000 = 55000 W/m²C
