Total No. of Questions : 12] [Total No. of Pages : 3 [3864] - 339 P 1349 B.E. (Chemical Engineering) PIPING DESIGN & ENGINEERING (2003 Course) (Elective - II) Time : 3 Hours] [Max. Marks : 100 Instructions to the candidates: 1) Answer three questions from Section I and three questions from Section II. 2) Answers to the two sections should be written in separate books. 3) Neat diagrams must be drawn wherever necessary. 4) Figures to the right indicate full marks. 5) Use of electronic pocket calculator is allowed. 6) Assume suitable data, if necessary. SECTION - I Q1) a) b) Water at 20oC flows in a 80 mm pipe at Reynolds number 80000. The pipe is estimated to have an equivalent sand grain roughness of size 0.16 mm. Determine the head loss expected in 300 m length of the pipe. How much head loss would be expected if this pipe were smooth, kinematic viscosity of water at 20oC is 10 6 m2/s. [8] Define economic velocity? Explain briefly the considerations in economic velocity for following piping systems i) Hot liquid flow. ii) Slurry flow. [8] OR Q2) a) b) Q3) a) b) Explain in detail pipe line networks and their analysis for flow in branches. [8] Discuss the procedure in determining pipe diameter for specified height of pipe wall roughness and the discharge? [8] Explain the desirable properties of piping materials for low temperature and high temperature services? [8] Explain the various types of pipe fittings in detail? [10] OR P.T.O.
