Answer:
h =12.9 w/m2 k
Explanation:
we know that thermal conductivity of air K at 0 degree celcius = 0.024 w/mk
T_S = 80 Degree celcius
temperature gradient = -43 degree C/mm = - 43*1000 / m
by fourier law
q = 1032 watt/m2
we know that from newton's law
q = h (T_s - T_∞)
1032 = h*(80 - 0)
h =12.9 w/m2 k
Answer:
B = 32.17 x 10^-8 Tesla
u = 8.24 x 10^-8 J/m^3
P/A = 24.72 W/m^2
Explanation:
E = 96.5 V/m
velocity of light, c = 3 x 10^8 m/s
Let B be the magnetic field.
The relation between the electric field strength and the magnetic field strength is given by
B = E / c = 96.5 / (3 x 10^8) = 32.17 x 10^-8 Tesla
Let u be the energy density.
u = 8.24 x 10^-8 J/m^3
Let Power flow per unit area is
P/A = u x c = 8.24 x 10^-8 x 3 x 10^8 = 24.72 W/m^2
