This is a complete question I am stuck in. Kindly answer as soon as possible.
A liquid metal flows at a mass rate of 3 kg/s through a constant heat flux 5-cm-i.d tube in a nuclear reactor. The fluid at 473 K is to be heated with the tube wall 30 K above the fluid temperature. Determine the length of the tube required for a 1-K rise in bulk fluid temperature, using the following properties: p = 7.7 x 10^3 kg/m^3v = 8.0 x 10^-8 m^2/sCp = 130 J/(kg K)k = 12 W/mKPr = 0.011 Kaufman's correlation: Nu = 0,625.(Re.Pr)0,4
Please help. I am not sure how to approach this problem. This problem involves heat transfer and internal flow within a pipe. Thank you.

200 pm 0.12 cm Fluid Stationary cylinder 4 In regions far from the entrance, fluid flow through a circular pipe is one-dimensional, and the velocity profile for laminar flow is given by u(r) = Umax(1 - r/R9), where R is radius of the pipe, r is the radial distance from the center of the pipe, and Umax is the maximum flow velocity, which occurs at the center. Obtain (a) a relation for the drag force applied by the fluid on a section of the pipe length L and (b) the value of the drag force for water flow at 20°C with R = 0.08 m, L = 15 m, Umax = 3 m/s, and u = 0.0010 kg/m.s. %3D
It says the answer is NOT 33.7 oC (see attached photo). What is the correct answer? Thank you.
Pinch temperature at hot stream is 70C, while at cold stream is 60C
Required Information Water at 10°C (p = 999.7 kg/m³ and u=1.307 x 103 kg/m-s) is flowing steadily in a 0.12- cm-diameter, 19-m-long pipe at an average velocity of 0.9 m/s. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the pressure drop. (You must provide an answer before moving on to the next part.) The pressure drop is 128.77 kPa.
4. An experimental test rig is used to examine two-phase flow regimes in horizontal pipelines. A particular experiment involved uses air and water at a temperature of 25°C, which flow through a horizontal glass tube with an internal diameter of 25.4 mm and a length of 40 m. Water is admitted at a controlled rate of 0.026 kgs-¹ at one end and air at a rate of 5 x 104 kgs¹ in the same direction. The density of water is 1000 kgm3, and the density of air is 1.2 kgm-³. Determine the mass flow rate, the mean density, gas void fraction, and the superficial velocities of the air and water. Answer: 0.02605 kgs-1, 61.1 kgm ³, 0.94, 0.822 ms-1, 0.051 ms-1
