The temperature of a hot gas stream flowing in a duct (90cm) length and (30cm) diameter is to be measured by using a spherical thermocouple junction (2mm) in diameter placed at the center of the duct. The duct wall is at (30 ° C) and the gas stream is at (110 ° C). If the heat is being transferred to the thermocouple at the rate of (560 W / m²) from the gas, and both the thermocouple and the duct are considered black, what will be the reading of the thermocouple?

Consider the case of liquid flow in a uniformly heated channel. Initially, heat flux is so low that it only increases the liquid sensible heat. We then start to increase heat flux until water starts to boil. We keep increasing heat flux until eventually we attain a specific value for heat flux at which the tube first experiences CHF. Under this condition at what point does CHF first occur?

A computer cooled by a fan contains eight printed circuit boards (PCBs), each dissipating 10 W of power. The height of the PCBs is 12 cm and the length is 18 cm. The clearance between the tips of the components on the PCB and the back surface of the adjacent PCB is 0.3 cm. The cooling air is supplied by a 10-W fan mounted at the inlet. If the temperature rise of air as it flows through the case of the computer is not to exceed 10°C, determine (a) the flow rate of the air that the fan needs to deliver, (b) the fraction of the temperature rise of air that is due to the heat generated by the fan and its motor, and (c) the highest allowable inlet air temperature if the surface temperature of the components is not to exceed 70°C anywhere in the system. As a first approximation, assume flow is fully developed in the channel. Evaluate properties of air at a bulk mean temperature of 25°C. Is this a good assumption?
