Calculations involving retention time involve the following formula, T =, where V is volume and Q is flow rate. Often times, you will be required to calculate the volume of more than one tank and determine a rate of flow, given a total retention time. Tank 1 Tank 2 Let's assume that the total retention time for the entire system is 55 minutes, and we want to know the inlet flow, given the dimensions of tank 1 are : 14m x 10m x 3 m, and tank 2 are: 5m x 10m x 3 m. Calculate the inlet flow.

How do I answer this question?

Water flows through a 125 mm diameter pipe at a velocity of 7.5 m/sec. Find the mass flow rate in kg/sec. NOTE: Do not write any unit to your answer, put your answer in a numerical form only and use up to 3 decimal places. ASAP PLS

i need help with the calculations.  i am messing up something in the math

Please help, will provide definitely helpful ratings for full solution. Thank u

If a liquid enters a pipe of diameter d with a velocity, v. what will irs velocity at the exit be if the diameter reduces to 0.5d?

A plugged dishwasher sink with the dimensions of 15 in. x 19 in. x 9 in. is being filled with water from a faucet with an inner diameter of 1 in. It takes 210 seconds to fill the sink to its rim. Imagine the plug of the sink leaks. If it now takes 230 seconds to fill the sink to its rim, estimate the mass-flow rate of the leak (in lbm/s). 1.1 X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. Ibm/s

1. A piston-cylinder is producing a viscous oil flow, which has the flow rate of Q, radius R=1.5 mm, and stroke L-5 mm. The fluid density is p = 800 kg/m³ and the viscosity is μ = 0.5 Pa-s. The pressure to drive the flow is p-6.25 Pa. a. How many non-dimensional groupings can be obtained? Derive them. b. If the flow transitions at Re = V(2R) =2300. Is the generated flow laminar or turbulent given Q=20 mL/s? c. Assume the pressure gradient is uniform on the cross-section and can be calculated using - The velocity profile in the cylinder is u(r) = [1-2²]. Sketch the velocity profile. Calculate the shear stress at the ax 2μ δχ cylinder wall and label the direction. d. Calculate the flow rate Q with the velocity profile in (c).. e. If the shear stress is uniform over the cross-section, i.e. T = C, what's the pressure gradient distribution and sketch it? L r L. R

On a single plot, plot three curves that show the relationship between the pressure generated by thepump as a function of flow rate of water at 20 °C through the three branches of the piping systemshown below. Delta P on y axis and flow rate on the x axis. The pressure range is 0 to 1 MPa. (Branches 1 and 3 are in the same plane; branch 2 is located 5 m above the other two branches. Pipe inner diameter: 0.0254 mPipe material: copperTypical mass flow rate of interest: 0.5 kg/sIgnore minor losses of tee's at points A and B and any features of branch 3Consider minor losses of two 90° elbows in branch 2
