An assembly line can produce 90 units per hr. The line hrly cost is $4500 on stright line ( the first 8 hrs). Workers are guaranteed a minimum of 6 hrs. There is a 50% premiun for overtime (time and a half), how ever productivity drops by 5%. What are the average and marginal cost per unit for the following daily quantities.
a. 450
b. 600
c. 720
d. 900
A 3 phase Y connected alternator is rated at 1600 KVA, 13500 V. The armature resistance and synchronous reactance are 1.5 ohms and 30 ohms respectively. Calculate the % voltage regulation for a load of 1280 KW at 0.8 leading power factor.
A long narrow rod has an atomic density of 5*1028 m-3. Each atom has the polarizability of 10-40 F m2. Find the internal electric field when an axial field of 1 V/m is applied.
A temperature sensor is specified to provide 2 mV/°C. When connected to a load resistance of 10 k ohm, the output voltage was measured to change by 10 mV, corresponding to a change in temperature of 10°C.
1. What is the effect of sampling at a higher rate on the error performance of a digital modulation scheme 2. Suppose 16QAM was the modulation scheme used for this lab; would the error performance
Determine the energy uses on farms in middle east and determine whether or not it is better to use a stand alone system or a grid connected system for the application on farms.
a ladder 61 ft. long is leaning against the side of a house. the base of the ladder is sliding away from the house at a rate of 6 ft/sec. At what rate is the top of the ladder sliding down the house when the base of the ladder is 11 ft. from the h..
A 300 V, 60 A, 1200 rpm series dc motor has an armature and series field resistance of .2 ohms each. When a .10 ohm resistance is connected in parallel to the winding, the motor's torque is doubled.
compute the fourier transform of the descret time signal x[n] = {C, n1
stochastic message signal, m(t), is transmitted down a (noiseless) cable channel by PCM, using an 8-bit code. If the ambient signal is equally likely to lie anywhere between its two extremes, (+/- mp), calculate the ration of the mean squared sign..
Simplify the following circuit. Line A goes into an INVERTER, then into a NAND Gate, then into an OR Gate, then travels into another NOR Gate.
Pure ethylene (C2H4) and oxygen are fed to a process for the manufacture of ethylene oxide (C2H4O) C2H4 + ½ O2? C2H4O The process flow diagram is shown below. The catalytic reactor operates at 300 °C and 1.2 atm. Under these conditions
