- what will be the pressure gradient (kpa/m) at L=30 cm through the nozzle? At L=0, the liquid flows inside the nozzle has a specific gravity S=6.1, at L=0, the velocity is 2 m/s while at L=70 cm, the velocity is 6 m/s. Assume steady and inviscid flow. The velocity varies linearly with distance through the nozzle. 70 cm mis 2ns 60 cm Liquidarrow_forwardFor a flow in the xy plane, the x component of the velocity is given as u=3x2y-y3. Determine the y component for steady state and incompressible flow. Does this result also apply to unstable, incompressible flow? Why is that? How many possible y components are there? Discuss.arrow_forwardYour team is designing a chemical processing plant. You are the liquid handling and transportation specialist, and you need to transport a solvent (μ = 3.1 cP, ρ = 122k kg/m3) from a storage tank to a reaction vessel. Due to other equipment constraints, the fluid velocity must be 0.8 m/sec, and you must use stainless steel piping (ε = 0.00015 mm) with a total length (L) of 12 m. Determine the pipe inner diameter (ID) you will need to achieve a pressure drop of 0.3 kPa. Use the Moody chart.arrow_forward
