Solution Summary

By responding to the questions, this solution answers this question: A fluid in an aquifer is 6.5 m above a reference datum, the fluid pressure is 1800 N/m2, and the flow velocity is 3.4 3 1025 m/s.

3. A piezometer is screened 723.4 m above mean sea level. The point-water pressure head in the piezometer is 17.9 m and the water in the aquifer is fresh at a temperature of 20°C.
(A)What is the total head in the aquifer at the point where the piezometer is screened?
(B) What is the fluid pressure in the aquifer at the point

A horizontal has a fluid flowing through it. The fluid(density = 1000kg/m^3) is flowing through it at the rate of 2 x 10^-4 m^3/s. The inside diameter of the larger portion is 3 cm and that of the diameter of the constriction is 1 cm. Find the pressure difference that exists between the larger and the constricted sections.

A pump is used to raise the pressure of diesel fuel. It is measured that power needed to drive this pump is 5 kW for the steady operation (dE/dt = 0 for the system) (m in = m out). The efficiency of this perfect pump is 100% (all the energy is used to raise the pressure of diesel fuel). The density of diesel fuel is 800

We would like to know the nature of the drag forces experienced by a sphere as it passes through a fluid. The sphere has a low speed. Therefore, the drag force is highly dependent on the viscosity of the fluid. The fluid density is to be neglected.
a) Use dimensional analysis to develop a model for drag force: F (MLT^-2) as a

Assume that the interior of the earth can be treated as an incompressible fluid in equilibrium. Let ? denote the density; take ? to be a constant; ? = M/V.
a.) What is the pressure within the earth p(r) as a function of distance from the center r?
b.) What is the pressure at the center, expressed in tons per square inch?

A patient is to receive an intravenous injection of medication. In order to work properly, the pressure of fluid containing the medication must be 109 kPa at the injection point. (a) If the fluid has a density of 1020 kg/m^3, find the height at which the bag of fluid must be suspended above the patient. Assume that the pressure
