Question 5. What is the terminal velocity (m / s) for a 4g particle which is falling in the water with projected area of 5 sq.cm ? The coefficient drag is given as 0.47 .

A pump system is used to move water at a flow rate of 30 L/s from a lower to a higher reservoir in a city with an elevation of 1000 m above sea level. The system is shown schematically in the figure below, with ∆?=30 m. Both the suction and delivery pipes have a diameter of 150 mm and an absolute roughness of 0.3 mm. The lengths of the suction and delivery pipes are 6 and 500 m respectively. Ignore local losses and assume a temperature of 15 °C.  a)Develop a mathematical expression for the system curve (i.e. the pumping head required as a function of the system flow rate) from basic principles. Name all mechanics principles implemented. b)Calculate the required pump working point. What is the flow regime of the pipe flow.  c)What power does the pump add to the water in the system?

Enter your answer in scientific notation. The discharge (Q) of a stream is the velocity (v) times the cross-sectional area (A): Q = vA.   What is the discharge of a stream with a velocity of 2.0 m/s  and a cross-sectional area of 55.7 m2?   z=  ? X 10^? m3 s

Problem 7.7 A mixing basin in a sewage filtration plant is stirred by a mechanical agitator with a power input W = F. LIT. Other parameters describing the performance of the mixing process are the fluid absolute viscosity μ=F.T/Ľ², the basin volume = Ľ³, and the velocity gradient G=1/T. Determine the form of the dimensionless relationship.

PLEASE PROVIDE A COMPLETE SOLUTION WITH FIGURE FOR ME TO FOLLOW :) ANSWER IS GIVEN FOR REFERENCE. THANK YOU!

the An orifice meter to carry water is calibrated with air in a geometrically similar model at prototype scale. Dynamically similar flow will be obtained when the discharge ratio (air to water) [Assume the ratio kinematic viscosity of air to water as 12.5] is

E. ( Geometric Probability Distribution) 1. An oil company has determined that the probability of finding oil at a particular drilling operation is 0.20. What is the probability that it would drill four dry wells before finding oil at the fifth one?

With velocity of 7 m/s in the 330 mm diameter pipe in the figure shown, determine the discharge in pipe 3 in m3/s. Assume f = 0.046 for all pipes and neglect minor losses.  The following are the properties of each pipe: Pipe 1 (Length=572 m, Diameter = 330 mm) Pipe 2 (Length=344 m, Diameter = 536 mm) Pipe 3 (Length=391 m, Diameter = 963 mm) Pipe 4 (Length=867 m, Diameter = 317 mm) Pipe 5 (Length=991 m, Diameter = 310 mm) Round your answers in 3 decimal places.
