1.A 50-m tape is used to measure between two points. The average weight of the tape per meter is 0.320 N. If the measured distance is 48.888 m, with the tape supported at the ends only and with a tension of 100 N, Find the corrected distance.
2.Write a VBA function that receives a gauge pressure and barometric pressure and then returns the absolute pressure. Have the function check whether the barometric pressure is zero, indicating that the program should use a default value of 1 atmosphere (or 14.696 psia) to the gauge pressure to calculate the absolute pressure
Water at 70oC (row = 1.94 slugs/ft3) flows out of a nozzle (diam. = 1in) with a velocity of 10 ft/s at an individual holding a protective shield. If the water deflects off of the shield perpendicular to the original stream in all directions
If the elevation difference between the water surfaces is y = 25 + x/11 metres, what minimum pipeline diameter will be required to convey the design discharge? Once your design is complete, determine the actual discharge. The value of x equals 23.
A 3000-lb car has a maximum speed (at sea level and on a level, paved surface) of 140 mi/h with 16-inch-radius wheels, a gear reduction of 3.5 to 1, and a drivetrain efficiency of 92%. It is known that at the car's top speed the engine is producin..
Base course aggregate has a target dry density of 119.7 lb/cu ft in place. It will be laid down and compacted in a rectangular street repair area of 2000 ft x 48 ft x 6 in. The aggregate in the stockpile contains 3.1 percent moisture.
If vehicle arrivals at the lot follow a poisson process, with arrival rate lambda = 0.2 vehicles/hour, what is the probability the lot is full at 9:15 AM. Assume that no one leaves during this period.
If the free surface at a distance from the axis of the vortex, which is sufficient for its effect to be negligible, is 180 mm above datum, what will be the height above datum of a point B on the free surface at a radius of 100 mm
A geotechnical report has suggested an allowable bearing pressure of 200kPa. Determine the minimum size of the pad footing 2 metres wide for a steel column if a factor of safety of 2.0 is recommended
Find the coeficient of friction between the trusses and the inclined. Three trusses are 1m long 1kg each.
consider a cylindrical nickel wire 2.0 mm in diameter and 3 x 10^4 mm long. Calculate its elongation when a load of 300 N is applied. Assume that the deformation is totally elastic.
Construction dewatering plays are very large role in the todays construction arena. Discuss the role water conditions plays in the planning and design of a temporary earth support system.
A 16-ft [4.88 m] span beam is fixed at one end and simply supported at the other end. A single concentrated load of 9600 lb [42.7 kN] is placed at the center of the span.
Ammonium (NH4+) is a weak acid with a pKa of 9.26. The dissociation is: NH+4 NH3 + H+. Calculate the mass of ammonium added to 1 L of water in order to obtain a pH of 4 at equilibrium.
