Consider a solid sphere of radius r=50 cm. The heat is generated steadily inside the sphere at a rate of (15000) W/m³. The conductivity of the sphere is 10 W/m.K. Surface of the sphere is cooled by cooling water whose temperature and convection heat transfer coefficient are 10°C and 125 W/m².K. Determine the temperatures at the center and surface of the sphere. Find the total heat transfer rate from the surface of the sphere. T=10 °C h=125 W/m².K r=50 cm Egen=(15000)W/m³ To=10 °C h=125 W/m².K
