Water flows through a 25 mm constriction in a horizontal 75 mm pipe. If the water temperature is 70 degrees C (vapor pressure of water at 70 degrees C is 31.2 kPa absolute), and the pressure in the pipeline is 275 kPa, what is the maximum flowrate which will occur without cavitation? The atmospheric pressure is 101.3 kPa. (Q = 0.013 m3/s)
A "slap shot" in the game of hockey can cause an increase in the velocity of a 5 oz puck from 2 ft/sec to 110 ft/sec. What would be the corresponding increase in the kinetic energy (ft-lb) of the puck.
determine the maximum negative moment in each span and maximum negative moment at each support. remember that live loads shall be placed so as to cause the greatest effect. specify the method that you used to determine the moments.
A person who retires at age 62 can receive Social Security benefits of $1537 per month, but by waiting for the full retirement age of 66, the person will receive $2057 per month.
A flat rectangular metal plate measures 17.63 + and - 0.02 inches by 26.85 + and - 0.04 inches. A circular hole of diameter 11.42 + and - 0.03 inches is cut out of the plate.
If the initial concentration of parathion in the runoff from the agricultural field is 3 ppb, the velocity of the river is 2.3 miles/day, how many days will the fish hatchery have to contain river water in holding tanks until the parathion concent..
The door of an oven has 27.9lb weight that acts vertically through point D. The door is supported by a hinge at point A and two springs that are symmetrically located on each side of the door.
The rod is made of a-36 steel and has a diameter of .25 in. if the springs are compressed 0.5 in when the temperature of the rod is T=40F, determine the force in the rod when its temperature is T=160 F.
Calculate the concentration of oxygen in the water in equilibrium (in mg/L) with the atmosphere near La Paz, Bolivia (3650 m), at 20 degrees Celcius.
A cylindrical soil, 75mm in diameter and 150 mm long, is radially compressed. The length increases to 153 mm and the radius decreases to 37.2 mm. Calculate: a) The axial and radial strains b) The volumetric strains
What is the maximum weight that can be suspended on a 16 Kg poll, 3/5 from the end. The maximum tension of the 30 degree guy-wire is 1500 N. Find the horizontal and vertical forces exerted on the poll by the hinge.
The circular top of a can has a radius of .0320m. the pull-tab has an area of 3.8x10^-4 m^2. The absolute pressure of the carbon dioxide in the can is 1.40x10^5Pa. find the force that these gas generates on the top of a can?
The footing is supported to carry a net safe load of 400 kN/m^2 with FS = 3. Given Ysat = 20.85 KN/m^3 and phi = 35 degrees, find the required width of the footing using Terzaghi's general shear failure criterion.
