L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...

A solute A is being transferred from a binary gas mixture of A and C into a pure liquid solvent B in a counter current packed tower with a cross sectional area of 0.2 m2. The inlet gas contains 5 mol% of A and its desired to recover 87% percent of A from the gas stream. The feed gas flowrate is 3.7 mol/s and the liquid solvent inlet flowrate is 13 mol/s. ky’ah = 40 mol/m3s and kx’ah = 60...

1. Water is flowing in a pipe as shown in the figure. The diameter of the cross section area A1 is twice the diameter of A2. The velocity of flow v1 is 2.00m/s while h and h2 are 5.00 cm and 30.0 cm, respectively. Take the density of water to be 1000. kg/m3 (a) Find v2 (b) Calculate the pressure difference P P2 between the two ends of the pipe 2

(b) A Newtonian liquid of viscosity 0.1 N s m2 is flowing through a pipe of 25 mm diameter and 20 m in length, and the pressure drop is 105 Nm2. As a result of a process change a small quantity of polymer is added to the liquid and this causes the liquid to exhibit non-Newtonian characteristics; its rheology is described adequately by the power-law model and the flow index is 0.33. The apparent viscosity of the modified fluid is...

8. (15 points) Water flows through a 3-in diameter pipe with a velocity of 25 ft/s as shown in the figure below. The relative roughness of the pipe is 0.0004 ft, and the loss coefficient for the exit is 1.0. Values for the liquid height in the tank (z) and the pipe length between the standpipe and tank (L) are 6 ft and 10 ft, respectively. Determine the height, h (ft), to which the water rises in the standpipe. P...
