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.

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...

Determine the overall heat transfer coefficient (U) in a heat exchanger that uses steam to heat water to the point of vaporization (in vacuum.)

Determine the overall heat transfer coefficient (U) in a heat exchanger that uses steam to heat water to the point of vaporization (in vacuum.) The system is non-insulated, so the heat lost to the surroundings must be taken into consideration. While I know that the heat Q = mCdT and the heat transfer rate q = UAdT(Log-mean), I am struggling to equate the two due to the heat lost to the surroundings. How do I go about determining the overall...
