The cylinder is made from aluminum with diameter and thickness of 5 cm and 1 cm respectively. The wall temperature in the insic of cylinder is 50°C, while the temperature of the air is 30°C. the coefficient of convection in the air is 10 W/m2 C. Calculate the heat loss from the cylinder per unit length! • Calculate the thickness of the insulation so heat loss from cylinder will decrease 50% of initial condition. Thermal conductivity of the isolator (k) : 0.5 W/m°C

Transcribed Image Text:Example
• The cylinder is made from aluminum with
diameter and thickness of 5 cm and 1 cm
respectively. The wall temperature in the inside
of cylinder is 50°C, while the temperature of
the air is 30°C. the coefficient of convection in
the air is 10 W/m2-C. Calculate the heat loss
from the cylinder per unit length!
• Calculate the thickness of the insulation so
heat loss from cylinder will decrease 50% of
initial condition. Thermal conductivity of the
isolator (k) : 0.5 W/m°C
