Q9) Consider a 50 cm diameter and 95 cm long hot water tank. The tank is placed on the roof of a house. The water inside the tank is heated to 80°C by a flat-plate solar collector during the day. The tank is then exposed to windy air at 18°C with an average velocity of 40 km/h during the night. Estimate the temperature of the tank after a 45 mm period. Assume the tank surface to be at the same temperature as the water inside, and the heat transfer coefficient on the top and bottom surfaces to be the same as that on the side surface.

![Q9)
Consider a 50 cm diameter and 95 cm long hot water tank. The tank is placed on the
roof of a house. The water inside the tank is heated to 80°C by a flat-plate solar
collector during the day. The tank is then exposed to windy air at 18°C with an
average velocity of 40 km/h during the night. Estimate the temperature of the tank
after a 45 mm period. Assume the tank surface to be at the same temperature as the
water inside, and the heat transfer coefficient on the top and bottom surfaces to be the
same as that on the side surface.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F74e78cee-722b-4b18-aee7-0380ad02165d%2F82086f6f-b791-43d5-97f9-af5c2a045451%2Fnsjhd8_processed.jpeg&w=3840&q=75)
