The velocity distribution for the flow of crude oil at 100?F (μ=8x10-5 lbf•s/ft2) between two walls is given by u = 100y(0.1 - y) ft/s, where y is measured in feet and the space between the
One means of determining surface level of liquid in a tank is by discharging a small amount of air through a small tube, the end of which is submerged in the tank, and reading the pressure on the ga
A 90° inverted cone contains water as shown. The volume of the water in the cone is given by V = (p/3) h3. The original depth of the water is 10 cm. A block with a volume of 200 cm3 and a specif
A pipe with a 2m diameter carries water having a velocity of 4 m/s. What is the discharge in cubic meters per second and in cubic feet per second.
Calculating the mass flow rate of the water discharged from a pipe.
An engineer is tasked with designing a pump station to convey wastewater at a flow rate of 250 m3/hr, to an equalization tank. A velocity of as a minimum 3 ft/s must be maintained in the pipe to pre
If a 200 N force F1 is applied to the piston with the 4 cm diameter, what is the magnitude of the force F2 that can be resisted by the piston with the 10 cm diameter? Ignore the weights of the pisto
Some skin divers go as deep as 50 m. What is the gage pressure at this depth in fresh water, and what is the ratio of absolute pressure at this depth to normal atmospheric pressure? Suppose T = 20&d
Find out the minimum volume of concrete (y = 23.6 kN/m3) needed to keep the gate (1 m wide) in a closed position; l = 2 m. Note the hinge at the bottom of the gate.

Explain two different energy alternatives to fossil fuels in detail. Discuss how they work, how they compare with fossil fuels, and their relative advantages and disadvantages.
What types of microstructures are produced by full annealing i) a eutectoid steel and ii) a hypoeutectoid steel.
Calculating the weight percent austenite and weight percent proeutectoid ferrite in hypoeutctoid plain carbon steel.
Macaroni and cheese packages specify how long to cook the pasta in boiling water. In general, foods that are cooked at lower temperatures need longer cooking times. On some packages, a longer leng
The ends of two thin glass tubes are stuck in the same pool of water. Though both tubes are thin, one tube has a smaller inside diameter (Tube 1) than the other (Tube 2). Both tubes are made of th
Inspection of a section of pipe reveals that the inside diameter is half the original value and the equivalent sand roughness Ks has increased from 0.2 mm to 1 mm. describe how these conditions woul
A diver is planning to salvage a Spanish galleon located in 200 feet of water. He plans to use a diving suit that will be supplied with air from a hose (suppose this to be amply sized) connected to
The owner wants to employ the similar pump to pump orange juice (S.G. 1.1). Explain how this change in fluid will affect: a) the rate of flow, b) pressure at the pump discharge, c) the energy requir
A Norwich MCE student is involved in a crucial out of class experiment. He is in his dorm room 34 feet above an historic rock wall. He thinks it may soon snow since his barometer reads 29.5 inches o
A manufacturer has come up with a new design for a globe valve. He has asked you to test the valve to conclude a value for the valve minor loss coefficient K while the valve is fully open. Explain h
If you had been tasked to remove the water from New Orleans after Hurricane Katrina would you select a radial flow, mixed flow or axial flow pump for this purpose? Explain your choice.
