Liquid chlorine is unloaded from rail tankers into a storage vessel. To provide the necessary NPSH, the transfer pump is placed in a pit below ground level. Given the following information, calculate the NPSH available at the inlet to the pump, at a maximum flow rate of 16,000 kg/h.
The total length of the pipeline from the rail tanker outlet to the pump inlet is 50 m. The vertical distance from the tank outlet to the pump inlet is 10 m. Commercial steel piping, 50 mm internal diameter, is used.
Miscellaneous friction losses due to the tanker outlet constriction and the pipe fittings in the inlet piping are equivalent to 1000 equivalent pipe diameters. The vapor pressure of chlorine at the maximum temperature reached at the pump is 685 kN/m2 and its density and viscosity, 1286 kg/m3 and 0.364 mNm-2 s. The pressure in the tanker is 7 bara.
A waste with a concentration of 0.1 gram per liter is to be introduced to a hazardous waste reactor that is to achieve 90% destruction. A reactant
Find infinite series converge and which diverge - You mix the vessels thoroughly so that each vessel contains a mixture of oil and vinegar. This caper is then repeated any number of times.
If the capacitor, consisting of three equal sections, is connected in delta across the supply lines, calculate the capacitance required in each section.
If this alternator is to generate 60-Hz voltages, find the new synchronous speed, and calculate the new terminal voltage for the same field current.
(Note that the number of parallel paths is equal to the number of poles for lap windings.)
Rotor resistance referred to the stator. Repeat the problem, given that the original rotor is rewound with the same number of turns as originally, but with one-half the original cross section of the conductor. Neglect the changes in the leakage fl..
A 30 mol% feed of benzene in toluene is to be distilled in a batch operation. A product having an average composition of 45 mol% benzene is to be produced. Calculate the amount of residue, assuming α = 2.5 and W0 = 100.
The concentration of this sample is changed such that its transmittance has increased to 57%. Calculate the new concentration of the sample.
Based on this brief description of the Head Master, draw a block diagram of how this device might work and the basic components that might be needed in the Head Master. Include in your block diagram the ultrasonic signal source, detectors, timers,..
As a system increases in volume, it absorbs 55.0 J of energy in the form of heat from the surroundings. The piston is working against a pressure of 0.502 atm. The final volume of the system is 57.7 L. What was the initial volume of the system if t..
