The drinking water needs of an office are met by large water bottles. One end of a .25 in diameter plastic hose is inserted into the bottle placed on a high stand, while the other end with an on/off valve is maintained 2 ft below th bottom of the bottle. If th water level in the bottle is 1.5 ft when it is full, determine how long it will take at the minimum to fill an 8 oz glass (=.00835 ft3) (a) when the bottle is first opened and (b) when th bottle is almost empty. Neglect frictional losses.
A cylindrical metal specimen 12.0 mm in diameter and 120 mm long is to be subjected to a tensile stress of 40 MPa . at this stress level the resulting deformation is totally elastic.
You measure an angle with a theodolite several times and record the following observations. What is your best estimate of the true value of the angle What is the standard error of the observations
A rod is subjected to a tensile load of 25k and has a diameter or 2in, determine the principle strains at a point on the surface of the rod
the block is fitted between the fixed supports. if the glued joint can resist a maximum shear stress of T(allow)=2ksi, determine the temperature rise that will cause the joint to fail. Take E= 10(10^3)ksi, v=0.2
Draw A flow net. Show flow lines, flow Channels, and Equipotential lines. Using flow nets, please provide an estimate of seepage rate below the dam. Your submittal will provide the basis for an environmental impact statement regarding the construc..
given: Vf=Vi + a t and Sf=Si + Vi t + 1/2 a t Cedar points millennium force accelerates from 10 mph to 93 mph in 4.5 seconds. assuming acceleration is constant, find acceleration in ft/sec^2 and distance traveled in meters
A tire carries a 5,000-lb load and has a pressure of 100 psi. The pavement has a modulus of elasticity of 43,500 psi. A deflection of 0.016 inches is observed at a point on the pavement surface 0.8 inches away from the tire load.
Farah Manufacturing wants it's investments to double in value in 4 years, what rate of return would it have to make on the basis of (a) simple interest (b) compound interest
The motor in the unit runs at 300 rpm and produces an unbalanced force of 60 lb at this speed. Neglect weight of the beams and assume 1% viscous deflection in the system; for steel E=30,000 ksi.
If the hydraulic head in the canal is 100 ft and in the drainage ditch it is 80 ft calculate the maximum mounding height and the mounding distance from the canal that will occur if the farmer irrigates at a rate of 2 acre-ft/acre/year.
A wastewater sample was diluted by turbidity free water; 5ml was diluted to 250 ml. Turbidity of the diluted sample was 2.3 NTU, what is the turbidity of the original sample
Assuming that the coefficient of friction between the tires and the pavement is 0.30, determine the braking distance downhill and the percent grade of the highway at that section of the road.
