Consider the following schematic for an experiemental methodology to measure the convection heat transfer coefficient distrubution on an airfoil. The metal sheathing is supplied with a heat generation rate of 20 * 106 W/m3. The thickness of the metal sheathing is t = 30 um, and the sheathing's thermal conductivity is k=25 W/mK. The 30 surface locations where the temperatures are measured are spaced evenly at 2mm apart. The measured temperatures are listed in the table below. Location Temperature (degrees...

Convection Heat transfer internal flow Consider water flowing in a heated tube. The tube is 14 m long with an inner diameter of 1 cm. The heat is added at 1500 W/m2 uniformly along the tube. Water flows at 0.3 m/s. Use the following water property ? = 1000 kg/m3, ? = 1.4 × 10?3 kg/m·s, cp = 4.2 kJ/kg·K, k = 0.58 W/m·K, and determine 1. Heat transfer coefficient at the tube exit. 2. Tube surface temperature at the...

The existence of convection heat transfer has been long used by traditional fishermen for fishing purposes.

The existence of convection heat transfer has been long used by traditional fishermen for fishing purposes. For example, by utilizing land breeze, the fishermen will go to the sea at night, and conversely, by utilizing sea breeze they will come back during the day. How this natural heat transfer can be used by the fishermen? Next, explain the mechanism of the occurrence of the land breeze and the sea breeze and their relation to the convection heat transfer events in...

What is the increase/decrease in overall company profits if this transfer takes place?

Sunland Company manufactures and sells high-priced motorcycles. The Engine Division produces and sells engines to other motorcycle companies and internally to the Production Division. It has been decided that the Engine Division will sell 12000 units to the Production Division at 1050 a unit. The Engine Division, currently operating at capacity, has a unit sales price of $1750 and unit variable costs and fixed costs of $1050 and $700, respectively. The Production Division is currently paying $1600 per unit to...

A steel pipe (k = 43 W/m K) carries a heat‐transfer fluid and is covered with a 2‐cm layer of calcium silicate insulation (k = 0.029 W/m K) to reduce the heat loss. The inside and outside pipe diameters are 5.25 cm and 6.03cm, respectively. If the inner pipe surface is at 150°C and the exterior surface of the insulation is at 25°C, calculate: (a) The rate of heat loss per unit length of pipe (b) The temperature of the...

The rate of heat transfer, Q [energy/time = power] through a pipe wall between a fluid and the surroundings depends on fluid properties: density (ρ), viscosity (μ), specific heat (cp [energy/temperature/mass]); and also on pipe and flow properties: the length (l), diameter (D), and thermal conductivity (λ [power/length/temperature]) of the pipe, fluid mean velocity (V), and the temperature difference (ΔT) between the pipe wall and the surroundings. Use dimensional analysis to express this system in terms of dimensionless numbers. The...
