Mechanical Engineering

q1) Fluid ( ρ = 850 kg/m3; μ = 0.08 Pa.s) flowsthrough a 4-cm diameter tube at 0.5 m/s. The Reynolds number of thefluid is

q2 ) An oil with ρ= 900 kg/m3 and ν=2x10-4 m2/s flows upward through an inclinedpipe of diameter 4 cm as shown in Fig. 1. The pressures at sections1 and 2 (L =11.3 m apart) are p1 = 359kPa and p2 = 201 kPa, respectively. Assumingsteady laminar flow, compute the average velocity; in m/s.

q3) Fluid ( ρ = 850 kg/m3; μ = 0.08 Pa.s) flowsthrough a 4-cm diameter tube at 50 m/s. The flow characterizesas:

Q4) The hydrodynamic entry length of laminar flow fluid ( S.G =0.985 ; ν = 1.47x10-5 m2/s) flowingthrough tube at 0.13 m/s is 27.6 cm. The tube diameter is:

Q) Fluid ( S.G = 0.985 ; ν = 1.47x10-5m2/s) flows through a 5-mm diameter tube at 3.3 m/s. Thehydrodynamic entry length of this flow is:

Q6) Fluid ( S.G = 0.985 ; μ = 1.47x10-2Pa.s) flows through a 15-cm diameter tube at 3.3 m/s. Thehydrodynamic entry length of this flow is:
