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 (c_p [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 Π group that includes Q˙ should be expressed as a function of the other Π groups.

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...

5. A power cycle receives energy QH by heat transfer from a high temperature energy source at TH = 2000 K and rejects energy QL by heat transfer to a low temperature energy sink at TL = 400 K. For each of the following cases determine whether the cycle operate reversibly, irreversibly, or is impossible. (a) QH = 1200 kJ, Wcycle = 1020 kJ. (b) QH = 1200 kJ, QL = 240 kJ. (c) Wcycle = 1400 kJ, QL =...

if you transfer heat energy to a perfectly insulated cup of some liquid (no heat energy can be transferred in or out through the walls) what determines how much the temperature changes? Does it depend on how much heat energy you transfer, how much liquid there is in the cup, what the liquid is, or what the initial temerpature of the liquid is? Which of these factors do you think make a differnce in how much the temperture rises?

An incompressible liquid flows through a straight horizontal pipe. Friction of the fluid within the pipe...

An incompressible liquid flows through a straight horizontal pipe. Friction of the fluid within the pipe causes a small amount of heat to be transferred from the fluid; to compensate, flow work must be done on the fluid to move it through the system (so W(dot)fl is greater than zero. a) How are V(dot)in and V(dot)out related, where V(dot) is the volumetric flow rate of the liquid? (Remember, fluid is incompressible) b) How must the pressures of Pin and Pout...

An incompressible fluid is flowing through a vertical pipe with a constriction. The wide section is 2.00 cm in diameter and is at the top of the pipe. The pressure of the fluid in the wide section at the top is 200 kPa. The velocity of the fluid in the wide section is 4.00 m/s. The narrow section is located 4.00 m below the wide section. What is the diameter of the narrow section for the pressure of the fluid...

A double-pipe heat exchanger operating in counter current mode is to heat a fluid(Cp 1.7 kJ/kg K) from 50°C to 95°C at a rate of 4.5 kg/s. The heating is to be accomplished by hot fluid (Cp=1.97 kJ/kg K) available at 200°C at a mass flow rate of 6 kg/s. The inner tube is thin-walled and has a diameter of 4 cm. If the overall heat transfer coefficient of the heat exchanger is 680 W/m2 °C, determine the length of...
