2. An 18-cm-long, 16-cm-wide, and 12-cm-high metal block (p = 8000 kg/m', c, = 400 J/kg°C, k=200 W/mK) initially at 20 °C is placed in an oven at 600 °C for heat treatment. The heat transfer coefficient on the surface of the block is 40 W/m "C. How long time is required for the iron block to reach a temperature of 400 °C? 1321 35°C Güneş 1407 20021
A 1.5m diameter spherical balloon containing air at (K + 10) kPa is cooled such that the volume is reducedby 25%. For the process, the pressure is proportional to the square of the sphere’s diameter. What is the workdone by the surrounding? NOTE: is K=821 asap
3. A well-mixed cement-lined storage tank contains water initially at 50°C. The water loses energy to its surroundings via conduction through the tank's concrete-lined walls. The tank sits in an unheated warehouse with an air temperature of 0°C. A diagram of the storage tank is shown below. The cement lining is 1.5-cm thick and has a thermal conductivity (htc) of 2.0 W/(m K). height = 1.5 m diameter = 2.0 m a. How long will it take (in minutes) for the water to cool to 40°C? b. Why might you be over- or underestimating the time it will take to cool the contents of the reactor?
