A 230-V dc shunt motor delivers 30 hp at the shaft at 1120 r/min. If the motor has an efficiency of 87% at this load, find:
(a) The total input power.
(b) The line current.
(c) If the torque lost due to friction and wind age is 7% of the shaft torque, calculate the developed torque.
A condenser is required to condense n-propanol vapour leaving the top of adistillation column. The n-propanol is essentially pure, and is a saturated vapourat a pressure of 2.1 bara.
A plant is producing 10,000 metric tons per year (10 kt/y or 10 kMTA) of a product. The overall yield is 70 wt% (0.7 kg of product per kg raw material). The raw material costs $500/metric ton, and the product sells for $900/metric ton. A process m..
1. Formation of kidney stones occurs when concentration of a poorly soluble salt (for example, calcium oxalate) in urine exceeds its solubility limit. Assume that a kidney stone has already formed and has traveled into the bladder. A bioengineer hypo..
If the stress at the center is 12,000 psi, what is the strain? Also, calculate the unit volume change e and the strain-energy density u at the center.
Assuming that the two unsealed faces of the wood immediately jump to an equilibrium moisture content of 10 lb H20 per 100 lb of dry wood, determine the time for the moisture to penetrate to the center of the slab (2 in. from either face). Assume a..
An elementary second order adiabatic reaction A+ B CD ? + is taking place in a CSTR. The feed to the reactor is equimolar A and B at concentrations of 2.4 mol/liter. The entering temperature is 300 K.
She believes she can extract 1700 kW of work and 220 kW of heat that will be used to boil water at 1 bar. Her process, whose details are yet to be determined, will receive streams A and B as inlet and will have a single outlet stream that will be ..
What is the best solvent to seperate phosphoric acid from aqueous calcium chloride solution
Is rusting a moderate reaction? Rusting is an example of what reaction?
To be satisfactory quality the ratio of 'A' to 'B' in the mixture must be 100 to 1or higher. 'D' reacts with both 'A' and 'B' as follows;A + D?R-rA= 21 CACDB + D?S-rB= 147 CBCDAssuming that the reaction go to completion, how much 'D' need be added..
In a specific rectification process , operating on ethanol and water mixtures, the vapor and liquid streams entering and leaving the column are those given in the table ethanol water mole% moles liquid entering top 75.1 24.9 liquid leaving bottom ..
