A liquid is entering a 10 m long pipe of 0.2 m diameter at 25°C with an average velocity of 0.02 m/s. The pipe is kept at a constant surface temperature of 40°C. Assume the flow is both hydrodynamically and thermally fully-developed in the pipe. Find out the outlet temperature. Justify if the assumption of fully-developed flow is appropriate. The properties of the fluid can be assumed constant with following values Density: 484.2 kg/m³; Specific heat capacity: 2802 J/kg.K; Thermal conductivity: 0.0904 W/m.K; Dynamic viscosity: 9.197 × 10-5 kg/m.s; Prandtl number: 2.85. 29.3 °C
Air is to be heated by passing it across the tubes of an in-line tube bundle consisting of 8 rows of 25 mm OD tubes in the direction of flow and 10 tubes in each row normal to the flow. Air approaches the tube bank in the normal direction at 30 °C and 1 atm with a mean velocity of 10 m/s. The tube spacing is 37.5 mm in both parallel and normal to the flow. Calculate the heat transfer from the bundle per m of length when the tube surface temperature is 90 °C.

You are designing a pin-style heatsink for forced cooling of an IC. A small fan blows RT air into the heatsink at about 2.3 ? ? . The aluminum pins are 2mm in diameter and have a constant surface temperature of 120°?. The heatsink is 100mm x 100mm and the pins have an inline arrangement with a transverse pitch of 4mm and a longitudinal pitch of 6mm. What is the total heat dissipation of this heatsink? The pins are 30mm high. Note RT=25 celsius
