A manufacturer of storage bins, with a budget of $10,000,plans to produce some open -top rectangular boxes with squarebases.The volume of each box is to be 125 cubic feet.Material forthe base costs $ 4 per square foot, and material for the sidescosts $2 per square foot.
Determine the dimensions of the box that will minimise thecosts of materials.Based on material costs alone,how many bins canthe manufacturer produce?
Suppose that the costs are expected to go up to $6 per squarefoot (base) and $4 per square foot (sides), by the end of theyear.How many bins can the manufacturer now produce if she stillwishes to minimze material costs?
To avoid the salinization of soil in a farming area, parallel drainage canals are to be installed to maintain the water table at a depth of at least 4m below the ground surface. It is thought that no evapo-transpiration would occur below that dept..
the pressure drop over 15 m of 2-cm diameter galvanized iron pipe is measured to be 60 Pa. If the pipe is horizontal, estimate the flow rate of water. use for water v=10^-6 m^2/s and density of water = 1000kg/m^3
Determine the flow rate of water (20 degrees celcius) that will cause a pressure drop of 17250 N/m^2 in 350m of horizontal, cast-iron pipe (d=60cm). assume minor losses are negligibe
question 1. the variation of 2sdt q with q of a basin is given by q 0.00152sdt q2nbsp 0.1952sdt q - 0.3833. the
Calculate soil moisture using daily (or any other scale) precipitation and temperature . Use the Richard's Equation and Darcy's law (Or any theory you like attached to soil moisture content determination ).
A square with the dimensions of .02m by .02m by .5m is attatched to a solid surface. If the forces on the rod are too large, it will either crush or be sheared off where it is atatched to the solid surface.
Two pipes, one circular and one square, have the same cross-sectional area. Which has the larger hydraulic radius, and by what percentage
a) The maximum flow rate that can be achieved without cavitation occurring in the piping system. b) The maximum elevation of the highest point of the piping system to avoid cavitation.
Calculate the radius of a palladium atom, given that Pd has an FCCcrystal structure, a density of 12.0 g/cm^3 , and an atomic weightof 106.4 g/mol.
The coordinates for Point A, Point B and Point C are 5859.28N, 9331.56E and 8501.95N, 7911.60E and 10,500.00N, 8000.00E respectively. An angle right of 220°31'00" is turned when the backsight is B
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
