Statement for Linked Answer Questions 14 & 15 A pipe is required to carry 100 l/s of crude 950 kg/m³, dynamic oil (mass density = 8x10 kg/m-sec) and still viscosity maintaining laminar flow. Flow is axisymetric and steady. 14. Determine the optimum diameter of the pipe, in mm. (a) 550 (b) 656 (c) 756 (d) 897 15. The power required for transporting the crude oil over (Approximately) one kilometer, is (b) 75 W (c) 186.6 W (d) 100 W (a) 50 W Codes: A (a) 2 4 (b) 4 1 3 (c) 4 3 1 (d) 17. Consider a steady, fully developed lamin flow of water through two pipes in series as shown in figure. The ratio h₁ / h₂ of the manometric fluid deflections considering only the friction losses in the pipes, for D 0.5D2 and L1 L2 is L₁ D₁ water Lo List-II 16. A larninar flow is taking place in a pipe. Match List-I (Term) with (Expression) and select the correct answer from the codes given below the lists. List-I (a) Discharge, Q AAP (b) Pressure drop, (c) Friction factor, if 18. The force F required on the piston discharge 500 mm³/s of water through syringe as shown, taking into account th frictional loss in the syringe needle only N.
