engineering recuitment GATE ME 2023-24 Test Series Heat Transfer Conduction Fourier Law and Thermal Conductivity
Temperature field inside a sphere of radius R = 1 m with origin at its center is T(x, y, z) = 100 – 70x + 51y – 80z – 10x2 – 20y2 – 20z2 . If thermal conductivity of the sphere material is K = 50 W/m.K and Fourier law of heat conduction is valid, net heat leaving the sphere per unit time in W is _______. [round off to one decimal place]
Enter numerical value using the virtual keypad. Round off where necessary.
