1.In a Venturi meter, (not shown) if the water surface dips a distance of 0.07m, what is the flowrate per width of the channel? The bottom of the meter is also 0.2m above the datum, (where D1=1.2m) giving D2=1.2-0.2-0.07=0.93 m. The density of water = 999 kg/m^3.
2.A level is setup midway between X and Y reads 5.572 ft on X and 4.946 ft. on Y. The level is setup very close to X and a reading of 4.666 ft. is taken on X. what should the reading be at Y to adjust any collimation error of the level?
3.A 2kg moves down a 45 degree incline at a constant velocity of .1m/s. What is the value of the kinetic coefficient of friction between the object and the incline?

A 3-m-thick, wide fill (γ = 19 kN/m3) is placed over a soil profile consisting of 6 m of plastic clay (γ = 16 kN/m3, e0, = 1.7, Cc, = 1.2, OCR= 1.4, Cr/Cc, = 0.15) over 10 m of organic silt
The heated water outflow from a nuclear power plant is cooled in a 50-m wide rectangular channel that has a discharge Q = 225.0 m^3/s. The Manning's n is 0.015 and the bed slope is 5.0 X 10^-4
Another way to treat acid mine drainage is to add limestone at the beginning of a narrow AMD stream to precipitate the metals. The first order rate constant is 10/day. Assume the stream is 3ft wide and 1ft deep
The velocity of a body is given by v(t) = 2t+t3. The body starts from rest at time t = 0 at position s(0) = (2,-10). What are the position and acceleration of the body as functions of time At what time, t, does the body cross the X-axis
For maximum undercooling, calculate the size of the critical radius and the number of atoms in the critical nucleus when solid copper forms by nucleation.
