- You are provided a horizontal tube with one entrance and one exit. Air (Cp = 1.005 kJ/(kg-K)) is passing through the pipe and is assumed ideal. The inlet conditions are 102 psia, 101 degrees Fahrenheit and velocity 9feet/second. Determine the outlet velocity (ft/s) and outlet temperature (degrees Fahrenheit) if the exit conditions are 2.1 psia. Assume the process occurs under adiabatic conditionsarrow_forwardQ2. A concentric annulus tube has inner and outer diameters of 25 mm and 100 mm, respectively. Liquid water flows at a mass flow rate of 0.05 kg/s through the annulus with the inlet and outlet mean temperatures of 20°C and 80°C, respectively. The inner tube wall is maintained with a constant surface temperature of 120°C, while the outer tube surface is insulated. Determine the length of the concentric annulus tube.

- Pressurized water (pin = 10 bar, Tin =110◦C) enters the bottom of an L = 12m long vertical tube of diameter D = 110 mm at a mass flow rate of m =1.5kg/s . The tube is located inside a combustion chamber, resulting in heat transfer to the tube. Superheated steam exits the top of the tube at pout = 7 bar, Tout = 600◦C. Determine the change in the rate at which the following quantities enter and exit the tube: (a) the combined thermal and flow work, (b) the mechanical energy, and (c) the total energy of the water. Also, (d) determine the heat transfer rate, Q˙.

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.
