A rectangular straight fin is 4-cm long and has a square cross-section of 5 mm sides. Its efficiency under a specific condition was found to be 93%. How many such fins are needed to be mounted on a 10-cm-by-10-cm surface so that the finned surface has an overall effectiveness of 10? Neglect radiation and assume adiabatic tip conditions.

What do you mean by fins? What is its significance. What are its applications. Explain it by giving three examples in details. This question is based on heat transfer.
Except for using table for getting thermal efficiency of fins, How can I derive a formula?
The wall of a 5 m high cylinderical steel tank (ks= 20 W/mK) of inner diameter 1.5 m and 200 mm thick contains hot oil at 100 C. On the outside of the tank 12 mm of spray urethane insulation is added to stop the oil from cooling. If the worst outside temperature is -6 , (hi = 16 W/m^2 K) and (ho = 5 W/m^2 K) how much heat needs to be added to keep the tank at 100 C for pumping reasons and what are the overall heat transfer coefficients Uo and Ui?
The hot water pipe of a heating system, 20 m long and 8 cm in diameter, was buried 80 cm below the soil surface. The outer surface temperature of the pipe is 60 °C.

There are 2 different types of fins: circular section and square section. Both fins are 30 cm length and they are made of copper with 380W/mK_conductivity. The circular section fin diameter is D = 3mm and the lateral width of the square section fin is W = 50 mm. The fin base temperature is -10°C. The fins are immersed in an oil bath at 50°C and perpendicular velocity to the axis of the fins. Obtain the maximum heat rate absorbed in each types of fin for an oil velocity of 60 m/s. Justify every calculation and assumption. Answer: 27.42W (circular section); 987.53W (square section parallel oriented); 1018.6W (square section oblique oriented)

Two nested spherical tanks with the internal and outer diameters of the 100 cm by 104 cm and 114 cm by 118 cm is used to store hot water at 100 C. Both tanks are made of boron fiber epoxy with different composite compositions. The thermal conductivity of the inner tank is 1.5 W/m K while the outer tank has a thermal conductivity of 0.5 W/m K. The gap between the tanks is filled with air (use properties of air at 50°C). The tank is located in an open environment at 0'C. The outer surface of the tank is white painted and heat transfer between the outer surface of the tank and the surrounding is by natural covection and radiation. The convection heat transfer coefficient at the inner and the outer surface of the pipe is h 20 W/m' K and h 10 W/m K. Determine; a. the rate of heat loss from the tank b. the inside, outside and intermediate surface temperatures. Hint: Take the outer surface temperature as 3°C for radiation calculations.
