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
There velocities will be different cuz velocity is a vector quantity ( depends on magnitude as well direction). Here same magnitude but different direction. So answer is velocity.
Answer:
Kinetic Energy = 1/2mv^2
Kinetic Energy = 1/2(150 kg)(20 m/s)^2
Kinetic Energy = 75 kg(400 m/s)
Kinetic Energy = 30000 J
Let me know if this helps!
