Draw a PLC ladder diagram for the situation described in Exercise 3.
Exercise 3
A small house has three windows and two doors. Each window and door has a switch attached such that the contacts close when a door or window opens. Draw a ladder logic diagram that will turn on a light if one or more windows are open or if both doors are open.
Calculate the rate of flow of heat down a copper rod 10 cm long with a diameter of 0.4 cm If the temperature gradient between its end is 1002C. Thermal conductivity of copper is 385 W/mK.
Using eye diagram drawings of PAM NRZ waveforms used to transmit bits in the baseband show and explain how awgn can effect bit error rates and how timing jitter can effect bit error rates.
A small gasoline engine can put out 18,000 N-m/min of mechanical power. The engine is used to drive an electrical generator that is 80 percent efficient. 1 N-m = 2.78 X 10-4 W-h. Find the output of the generator in Watts.
A 480 V permanent magnet ac motor is consuming 10 kW at power factor 0.80 lagging. Its speed is 1800 rpm. The winding resistance is 0.5 ohms per phase. Core losses are 100 W. Mechanical losses are 250 W. Stray losses are 1.5% of the input power
A 9-kVA, 208 V, 1200-rpm, three phase, 60 Hz, Y- connected, Synchronous generator has field winding resistance of 4.5ohm. The armature winding impedance is 0.3+j5 ohms per phase. When the generator operates at its full load and 0.8 lagging
Design a filter for a biomedical instrument to eliminate DC (f = 0), 500 Hz tone, and its corresponding harmonics. The system sampling rate is 2,000 Hz. Place all the required poles at the origin to obtain a FIR filter.
How will the reading of two ammeters compare if they are placed in series in a circuit Will the answer to this question be different if the resistance of the two ammeters is not the same
Design 3 stage amplifier with the following requirement input signal = 5 mV with R=10k ohms over all gain > 1000 power supply: Vcc = 5V, Vee = -5V Rin > 1 Mega Ohms Rout = 100 ohms 1st Stage BJT must use inverting
Communication and Other Areas of Diversity
A three-phase 5 hp, 208 V motor has an efficiency of 92%, and a power factor of 0.87 (lagging) when it runs at full power. Calculate the motor phase currents and line currents if the motor is wye connected, and delta connected.
