A Rankine-cycle steam power plant has a 5-MPa/450C throttle and 10-kPa condenser pressure. What are the net work, steam generator heat addition, thermal efficiency, heat rate, and turbine exit quality? What is the Carnot efficiency corresponding to the temperature extremes for this cycle?
Solve for the cases of (a) an 85% efficient turbine, (b) an 85% efficient pump, and (c) both together. What conclusions may be inferred from the results?
Calculate the probability that the system will fail in 3,000 hours. Supposing no failure of any component occurs in 5,000 hours of operation. What would be your revised estimate of failure rates of the components in your system?
Devise a detailed algorithm for a ring with p nodes so that each node would atttain the final sum of original node values. Determine the worst case communication steps for the algorithm.
Suppose station A and B are interconnected through two parallel unreliable links, where each link has a failure probability of 0.1. Calculate the average seconds per day when A and B lose communication.
An AM broadcast receiver's pre-selector has a total effective Q of 90 to a received signal at 1180 kHz and uses an IF of 455 kHz. Calculate the image frequency and its dB of suppression.
Signal transduction refers to any process of changing one signal to signal of another type. An example would be a series of pulsing lights into the sound for the word: "Help". Discuss how this transduction could be done by a device.
f(t) = t. B. f(t) = Sin wt find F(s). C. f(x) = y" + 2y' +y D. f(x) = y"' +4y" + 6y' + 9y. E. Given a serious electrical LRC circuit with an input source of 3Sin wt find the current i(t) expressed as I(s). Hint: use jwL and 1/jwC and w = 2pief
A HCS12 ATD is set to 10-bit unsigned mode. The voltage references are set to ground and 1.0V What is the ADT output for a temperature of 81 degrees The temperature sensor measures 0 to 100 degrees with an output of 10 mV/degree.
1) 70 lbs/hr of steam at 300 psia, 500oF passes through a turbine which expands it to a pressure of 30 psia. If the turbine operates with an efficiency of 70%: a) What is the temperature of the steam leaving the turbine b) What is the quality (% v..
A batch process which involves filling a tank with liquid, mixing the liquid and draining the tank, is automated with a PLC. The specific sequence of events is as follows
Characteristics of a filter, A filter has the following characteristics: Attenuation = 3.0 dB from 0 Hz to 2 kHz. From 2 kHz to 20 kHz attenuation increases from 3 dB to 23 dB in a straight line when plotted on axes of power in decibels (vertical a..
