An 8-inch water main with a flow rate of 14 ft3/sec raises 100-feet. At the beginning of the main the pressure is 110 psig and drops to 50-psig at the end. The calculated Hl = 11.7 m.
a.) Elevation Head
b.) Pressure Head
c.) Velocity Head
The divers work at a depth of 15 m and the seawater density is 1027 kg m-3. They are known to consume 130 litres of air at the ambient temperature is 10oC over the time taken to do the job.
Ignoring both axial and shear deformations and using the unit force method, calculate the vertical displacement of joint B.
A 3-point bending test is performed on a 10 mm diameter rod of Silicon Carbide. The distance between the supports is one foot. If the load at fracture is 10,000N, what is the flexural strength of the rod
When 0.3 m^3/s water flows through a 150 mm constriction in a 300 mm horizontal pipeline, the pressure at a point in the pipe is 345 kPa, and the head loss between this point and the constriction is 3 m.
It has been determined experimentally that the reaction follows frst order kinetics with respect to both oxygen andhydrogen sulfide concentrations: d[H2S]/dt =-k[H2S][O2]
The mass m, stiffness k, and natural frequency fn of an undamped SDF system are unknown. These properties are to be determined by harmonic excitation tests. at an excitation frequency of 4 Hz, the response tends to increase without bound.
A particle is traveling in a straight line at a constant speed of 22.9 m/s. Suddenly, a constant force of 10.7 N acts on it, bringing it to a stop in a distance of 63.6 m.
at a railroad crossing, an overpass must be built centered over the tracks at a height of 24ft and be 200ft long. the existing highway has a design speed of 50mi/hr.
