A four-pole, dc series motor has a lap-connected, two-layer armature winding with a total of 400 conductors. Calculate the gross torque developed for a flux per pole of 0.02 Wb and an armature current of 50 A. (Note: The number of parallel paths is equal to the number of poles for lap windings.)
The formation of ice during colder weather helps temper the seasonal transition to winter. This is mainly because
A balanced three-phase, wye-connected, 2400- V, 60-Hz source supplies two balanced wye connected loads in parallel. The first draws 15 kVA at 0.8 power factor lagging, and the second needs 20 kW at 0.9 power factor leading.
The line is commercial steel pipe, 25 mm internal diameter, length 120 m. The properties of the fluid are: viscosity 0.99 mNm-2 s, density 998 kg/m3. Calculate the total pressure drop due to friction when the flow rate is 3500 kg/h
Water will flow inside the tubing, and a hydrocarbon vapor will condense on the outside of the tubing.
Commercial cold packs and hot packs are available for treating athletic injuries. Both types contain a pouch of water and a dry chemical. When the pack is struck, the pouch of water breaks, dissolving the chemical, and the solution becomes either ..
A three-phase, 60-Hz substation bus supplies two wye-connected loads that are connected in parallel through a three-phase feeder that has a per phase impedance of 0.5 + j2 Ω. Load 1 draws 50 kW at 0.866 lagging PF, and load 2 draws 36 kVA at 0.9 l..
A standard practice in refineries is to use a holding tank in order to mix the light naphtha output of the refinery for quality control. During the first six hours of operation of the refinery, the stream feeding the holding tank at 200 kg/min had 30..
A steam press at 650Kpa + dryness fraction of 0.9% flows along a pipe at a rate of 3.5Kg per second. Steam mixes with additional steam that has been throttled from a pressure of 2000Kpa to a pressure of 800Kpa which enters from a branch pipe. If t..
Choose an initial guess for reactor temperature and pressure within the range provided and simulate the process described - Determine a metric to quantify the reactor performance then use this parameter to optimize the reactor temperature and pressu..
The overall reaction in a commercial heat pack can be represented as: 4Fe(s)+ 3O2(g) yields 2Fe2O3(s); delta H=1652 kJ a. How much heat is released when 4.00 mol iron is reacted with excess O2?
determine the unknown process variables.
