1.A smooth nozzle with a tip diameter of 2 inches terminates a 6 in waterline. Calculate the mean velocity of efflux from the nozzle when the velocity in the line is 10 ft/s.
2.A student trying to test the braking ability of his car, determined that he needed 15 m more to stop his car downhill on a particular road than uphill when driving at 90 km/h. 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.
The vehicle was estimated to hit the light pole at 30 mph. The skid was 650 feet long. How fast was the car traveling before applying the brakes
A container ship carries 2000 units. It must be unloaded andre-loaded in a 48 hr turnaround. Two cranes are available. Find the rate that the trucks line up, load and pass under each crane.
On a 20 ft cantilever beam, Load W1=200 or W2=500 or both may be applied at the midpoint B or at the end of the beam C. The bending moment induced at th fixed support A, MA, will depend on the magnitude of the loads at B and C.
With air pollution control equipment in place, plot the contours for a ground level concentration that is half and ¼ of the maximum value and indicate on your plot the location of the stack and the location of the point where the maximum ground level..
