In a quenching process, a copper plate of 3 mm thick is heated up to 350°C and then suddenly, it is dropped into a water bath at 25°C. (1) Calculate the time required for the plate to reach the temperature of 50°C. The heat transfer coefficient on the surface of the plate is 28 W/m2-K. The plate dimensions may be taken as length 40 cm and width 30 cm. (2) Also calculate the time required for infinite long plate to cool to 50°C. Other parameters remain same. (3) Calculate the heat transfer rate loss of the plate when it is at 50°C. Take the properties of copper as: CP = 380 J/kg-K, ρ = 8800 kg/m3, k = 385 W/m-K

Question
In a quenching process, a copper plate of 3 mm
thick is heated up to 350°C and then suddenly, it is dropped into a water bath at 25°C.
(1) Calculate
the time required for the plate to reach the
temperature of 50°C. The heat transfer coefficient
on the surface of the plate is 28 W/m2-K. The plate
dimensions may be taken as length 40 cm and
width 30 cm. (2) Also calculate the time required
for infinite long plate to cool to 50°C. Other
parameters remain same. (3) Calculate the heat
transfer rate loss of the plate when it is at 50°C.
Take the properties of copper as:
CP
= 380 J/kg-K, ρ = 8800 kg/m3, k = 385 W/m-K
