A stream of liquid moving as low speed leaves a nozzle pointed directly downward. The velocity may be considered uniform across the nozzle exit and the effects of friction may be ignored. At a Nozzle exit the jet velocity and area are V and A, respectinely. Determine the variation of jet are with elevation.
Using pie method, derive an expression for the velocity of a jet of viscous liquid issuing from an ori ce under static head if this velocity depends only on head, ori ce diameter, acceleration due to gravity, viscosity and density of fluid.
If the pulleys are fixed to the shaft, determine the magnitude of the tension T and the x,y,z componenet sof reaction at the smooth thrust bearing A and smooth journal bearing B.
A vane, 10 cm long and 8 cm in diameter, was pressed into soft clay at the bottom of a bore hole. Torque was applied and gradually increased 45 N-m when failure took place. Subsequently the vane rotated rapidly so as to completely remould the soil..
The pollutant has a reaction rate coeeficient k of 0.25/day. Assuming is pollutant is well mixed in the lake, find the steady-state concentration of pollutant in the lake.
Suppose that a person who boards the elevator on the ground floor gets off on the fifth floor. Assuming that the elevator has achieved operating speed by the time it reaches the second floor and that it is still moving at its operating speed as it..
Undrained Shear box tests were carried out on a series of soil specimens with the following results Total Normal Stress (kPa) Total shear stress at failure (kPa) Determine the cohesion and the angle of friction of the soil
An asphalt concrete mixture includes 94% aggregate by weight. The specific gravities of aggregate and asphalt are 2.65 and 1.0, respectively. If the bulk density of themix is 147 pcf, what is the percent voids in the total mix
A gate having the cross section is 4 ft wid and is hinged at C. The gate weighs 18,000 lb, and its mass center is 1.67 ft to the right of the plane BC. Determine the vertical reaction at A on the gate when the water level is 3 ft above the base.
A 780-g mass is attached to a vertical spring and lowered slowly until the mass rests at its equilibrium position 30 cm below the original length of the spring. It is then set into simple harmonic motion of amplitude 5 cm.
Determine the rate of ammonia (NH4-N) utilization and the biomass growth rate for the following conditions: µm = 0.50 g VSS/g VSS-d Ks = 0.50 mg/L X = 10 mg/L S = 40 mg NH4-N/L
Natural gas is stored in very large vessels consisting of a floating tank and a liquid seal. The pressure in the tank is constant because the weight of the floating tank is constant. In the morning, the temperature of the natural gas is 300 K.
A backsight reading of 2.56 was obtained with rod at A and a foresight reading of 7.45 was obtained with the rod at the trial point B. If B is located 37.00 feet from the center line of a planned 50-foot wide road, is the catch point located uphi..
