The cash flow of alternatives J and K is shown below. If the interest rate is 10% per year, which alternative should be selected. Perform a Present Worth analysis.
Year J K
0 -100,000 -190,000
1-3 -20,000 -10,000

The fluids do not mix and the atmospheric pressure is 1.01 x 105 N/m2. Determine the gauge pressure head and the absolute pressure head in metres of water at i depth of 6.6m below the free surface.
A long trough is supported by a hinge along its lower edge and a series of horizontal cables attached to its upper edge. Determine the tension in each of the cables, at a time when the trough is full of water.
If the river depth is larger than the subcritical sequent depth, a submerged hydraulic jump forms. Sometimes, concrete blocks called "baffle blocks" are placed on the stilling basin floor to help the hydraulic jump form within the basin.
Determine the excess pressure inside an 0.5-in-diameter soap bubble floating in air, given the surface tension of the soap solution is 0.0035 lb/ft.
Properties of frozen tissues have been measured as part of understanding the response of tissue to cryopreservation. In one set of experiments, frozen bovine carotid arteries were tested in uniaxial tension.
What is the tension in the cable connecting the boat to the pier Angle of spray 50 degrees off horizontal axis and is spraying toward the pier and pushing the boat away from the pier.
Water from a lower reservoir (water surface elevation) 500 m is pumping to the upper reservoir (water surface elevation 600 m) through a 5000 m long straight pipe with 0.5 m diameter.
The canal shown below is to be widened so that it can carry twice the amount of water. Determine the additional width L required if all other parameters (i.e. flow depth, bottom slope, surface material, side slope) are to remain the same.
The u-tube manometer has legs of unequal internal diameter d1 and d2, which are partially filled with immiscible liquids of density1, and density2 respectively and which are open to the atmosphere at the top.
A particle is traveling along a circular curve having a radius of 13 m. If it has an initial speed of 21m/s and then begins to decrease its speed at the rate of at = (-0.25s)m/s2
Investigate the possibility of environmental problems that faced by the area of disaster.
Two passenger cars are traveling at 65 MPH on a highway moving in the same direction in the same lane. The cars are separated by 25 feet for every 10 MPH of their speed. The coefficient of friction (skidding resistance) between the tires and the r..
