A fluid is entering into a circular pipe in which it is heated up. Temperature at the inlet and mass flow rate of the fluid are given as 25 °C and 0.02 kg/s respectively. Pipe radius is measured as 3 cm. You can assume fully developed conditions for the whole pipe length of L = 4 m and corresponding convection coefficient equals to 32 W/m²K. It is also observed that we have uniform surface heat flux of 800 W/m² . Under these conditions (Cp = 1004 J/kg s): a) Please find the total heat transfer rate and the average temperature of the fluid at the outlet. b) Please calculate surface temperatures at the pipe inlet and outlet.

A hot fluid passes through a thin-walled tube of 10 mm diameter and 1 m length, and a coolant at T∞ = 25°C is in cross flow over the tube. When the flow rate is m = 18 kg/h and the inlet temperature is Tm,i = 85°C, the outlet temperature is Tm,o = 78°C. Assuming fully developed flow and thermal conditions in the tube, determine the outlet temperature, Tm,o, if the flow rate is increased by a factor of 2. That is, m = 36 kg/h, with all other conditions the same. The thermophysical properties of the hot fluid are ρ = 1079 kg/m³, cp = 2637 J/kg · K, μ = 0.0034 N · s/m², and k = 0.261 W/m · K.

The liquid food is flowing through an uninsulated pipe at 90 °C. The product flow rate is 0.25 kg/s and has a density of 1000 kg/m³, a specific heat of 4 kJ/(kg K), a viscosity of 8 x 10^-6 Pa s, and a thermal conductivity of 0.55 W/(m K). Assume that the change in viscosity is negligible. The internal diameter of the pipe is 25 mm with a thickness of 3 mm made of stainless steel (k = 15 W/(m °C)). The outside temperature is 15 °C. If the outer convective heat transfer coefficient is 18 W/(m² K), calculate the heat loss at steady state per meter of pipe length. a. Find the convection coefficient in the pipe = Answer W/(m² °C). b. Calculate heat loss per meter of pipe length = Answer watt.
