1.A pump of what power is required to pump 0.56 m3/s of water from a reservoir of surface elevation 30 m to one of surface elevation 75 m, if in the pump and pipeline 12 m of head are lost ?
2.A water pipe gradually changes from 6 in to 8 in diameter accompanied by an increase in elevation of 10 f t. If the pressure at the 6 in and 8 in sections are 9 psi and 6 psi respectively, what is the direction of flow for 3 cfs flow ?
3.When 0.3 m^3/s water flows through a 150 mm constriction in a 300 mm horizontal pipeline, the pressure at a point in the pipe is 345 kPa, and the head loss between this point and the constriction is 3 m. Calculate the pressure in the constriction.
4.Three reservoirs are connected by three pipes with hA = 100 f t, hB = 20 f t, hC = 0 f t, l1 = 1000 f t, l2 = 500 f t, l3 = 400 f t and D1 = D2 = D3 = 1 f t. Determine flow rate into or out of each reservoir if friction in each pipe is 0.02. Neglect minor losses.
Design a logic circuit that, when enabled with an active-high signal named en, will detect four different ranges of values for a 5-bit input number.
A piston-cylinder device contains 2 kg saturated water vapor at 600 kPa. The water expands adiabatically until the final pressure is 100kPa. And 1,465 kJ work is produced.
Determine the mass and specific volume of argon gas in a vessel at 150 kPa and 20°C. The vessel is spherical, with radius 5 m.^5
When theta=0 degrees , the assembly is held at rest, and the torsional spring is untwisted. If the assembly is released and falls downward, determne the angular velocity at the instint theta=90.
A 110 cm^3 sample of wet soil has a mass of 106 g and a degree saturation of 100%. When oven-dried, the mass is 81 g. Determine the 1) water content, 2) specific gravity, 3) void ratio, and unit dry weight of soil particles.
A steam locomotives had scoops installed that took water from a tank located between the tracks and lifted water into the tender. To lift the water 12 ft with a scoop, neglecting all losses, what speed in mph is required
an uncontrolled mosaic is required for an environment project using 1/30000 photos. only the central area of each photo is used for the mosaic- an area about the center measuring 4.5x4.5 inches
A 0.02wt% C steel is to be carburized at 1200°C in 4 hrs with a point 0.6mm beneath the surface reaching 0.45wt%C. calculate the carbon content required at the surface of the steel.
Draw an inverted bowl – i.e., a horizontal line (exactly 10 inches long), with a big semi-circular upside-down “U” connecting the ends of that horizontal line. This is a picture of the ground and sky. Draw a little tiny person (you) at the mid-point ..
