H.W4: The average heat transfer coefficient for flow of 100°C air over a flat measured by observing the temperature time history of a (2L=3Cm) thick slab exposed to 100°C air. In one test run, the initial temperature of the pl (210°C) and in (5 minutes) the temperature decreased by (40°C). Calculate transfer coefficient for this case. [Taking the property value of p=9000kg/m', C=0.38 kJ/kg.°C, k=370W/m.°C and h=90W/m².°C].

Help me please
Show your complete solution.
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
