The temperature of flue gases flowing through the large stack of a boiler is measured by means of a thermocouple enclosed within a cylindrical tube as shown. The tube axis is oriented normal to the gas flow, and the thermo couple senses a temperature T, corresponding to that of the tube surface. The gas flow rate and temperature are designated as the

- Consider the shell and tube heat exchanger where liquid A of density pa is flowing through the inner tube and is being heated from temperature Tat to Taz by liquid B of density pe flowing counter-currently around the tube The temperature of liquid B decreases from Ten to Tea. In many practical situations the tubular heat exchanger is modelled using simple ordinary differential equations. This is possible if we think about the heat exchanger within the unit as being an exchanger between two perfect mixed tanks.

A thermodynamic analysis of a proposed Brayton cycle gas turbine yields P= 5 MW of net power production. The compressor, at an average temperature of T. = 400°C, is driven by the turbine at an average temperature of T₁ = 1000°C by way of an L = 1m-long, d= 70mm - diameter shaft of thermal conductivity k = 40 W/m K.

(1965) in a series of classic experiments studied the flow of blood in capillary tubes of various diameters. The blood had a hematocrit of 39.3 and the temperature was 20°C. They measured the pressure drop as a function of the flow rate for five tube diameters ranging from 288 to 850 μm. When they expressed the measured pressure drops in terms of the wall shear stress, and the volumetric flow rates in terms of the reduced average velocity, all of the data for the various tube sizes formed, within the experimental accuracy, a single line as predicted by the Rabinowitsch equation expressed in terms of reduced average velocity. From their results they provide the following values of the Casson parameters at 20°C: τy = 0.0289 dynes cm−2 and s = 0.229 (dynes s cm−2)1/2. Using these values for τy and s, show that the equation below for reduced average velocity provides an excellent fit to their data summarized in the following table.

- When viscous dissipation is appreciable, the energy balance of a convective system must include the viscous effects of the fluid, so a third term is added to the energy balance: A slide bearing (pillow block) can be idealized as a static plate and a plane that moves parallel to it. The rotary axis of such a system has a diameter of 100 mm and rotates at 3600 rpm inside the bearing, which has a gap between the plates of 0.5 mm. The system is lubricated by oil, with a density of 800 kg / m, a viscosity of 0 01 kg / ms and a thermal conductivity of 0:14 W / mk. The top and bottom surfaces of the bearing are at 60 ° C.
