13. An open tank contains liquid 8 m deep of unit weight of 9 kN/m3, water of unit weight of 9.81 kN/m3 is poured over the liquid and the the total depth of both liquids is 5 m. Obtain the gage pressure in KPa in the interface of the two liquids

Direction: Choose A- When both statements are true; B - When both statements are false; C- When the first statement is true and the second statement is false; D- When the first statement is false and the second statement is true. First Statement: The piezometric surface of an aquifer confined by an aquiclude is higher than that of an unconfined. Second Statement: Hydraulic conductivity is a measure of permeability or impermeability of a geologic unit. OA B. D.

A long, straight, horizontal 1000 ft length of 2 ft diameter pipe carries a 60°F water flow of 30 cfs. At this temperature, the water density is 1.94 slug/ft³, and the viscosity is 2.35x105 slug/ft-s. The equivalent sand grain roughness of the pipe is 0.0033 ft. What is the pressure drop over this length of pipe?

The velocity distribution near the solid wall at a section in a laminar flow is given by u = 5.0 Sin (5πy) for y ≤0.10 m. Compute the shear stress at y=0, (ii) y=0.06 m and (iii) y=0.12 m.. The dynamic viscosity of the fluid is 5 poise.

The gas storage tank consists of a cylindrical section with two hemispherical endcaps. The cylinder has a diameter of 2 m and a wall thickness of 15 mm. If the allowable normal stress of the tank wall material is 150 MPa, find the maximum allowable internal pressure in the tank.

Which of the following statements about HGL and EGL is correct? O For any pipe will a constant wall thickness, the slopes of EGL and HGL will be constant. O If the EGL falls below the pipe, then pressure head is negative, indicating a potential location of cavitation. O When a flow passage decreases in diameter, the distance between the EGL and HGL will increase. O When a pipe discharges into the atmosphere, both HGL and EGL will coincide with the system because pressure head is zero at these points.
