Consider a regenerative Rankine cycle with a 600_C and 4-MPa throttle, a 5-kPa condenser, and an open feedwater heater at 500 kPa. Turbine efficiencies are 85%. Neglect pump work. (a) Draw labeled, coordinated T-s and flow diagrams. (b) Determine the fraction of the throttle mass flow that passes through the extraction line. (c) Calculate the turbine work per unit mass at the throttle. (d) Calculate the cycle efficiency, and compare it with the simple-cycle efficiency. (e) Calculate the heat rate
Compute the amount of time required to deliver 10 frames to the receiver with stop-and-wait flow control. Assume that all frames and ACKs are received correctly.
Which sample produces greater Hall voltage: long and narrow or short and wide Thickness (d) is same in both the cases. With little explanations please. 1) If the concentration of scattering centers increase in the semiconductor, would it increase o..
Bode plots were introduced in my second circuit analysis class, but I really didn't think it was important because it looked like an outdated tool no longer in use.
Design a circuit that, given a 2-bit value, will light a LED corresponding to that value. One of four LEDs should be lit for each of the four possible input values (binary 0 through 3).
Now, suppose that an initial voltage of 1V is present at the capacitor at zero time (t = 0). Will the behavior of the circuit when a step input is applied still yield an exponential rise or will the behavior be of some other type
1.A liquid has an enthalpy of vaporization of 30.8 kJ/mol. At 275 K it has a vapor pressure of 117 mmHg. What is the normal boiling point of this liquid 2. In a certain mountain range, water boils at 94°C. What is the atmospheric pressure under the..
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.
A 1.80kg , horizontal, uniform tray is attached to a vertical ideal spring of force constant 195N/m and a 290g metal ball is in the tray. The spring is below the tray, so it can oscillate up-and-down.
Describe the charge diffusion and drift in a PN junction, without and then with an applied voltage
A penstock is used to bring water from behind a dam into a turbine. the effective head is 20 m and the flow rate of water is 50m^3/s. Compute the power of the water exiting the penstock.
write a program that calculates the quadratic equation. the program should be able to compute imaginary numbers (i.e. sqrt(-1)). finally, output the tow result. hint: the computer cannot directly compute imaginary numbers
Consider the financial aspects of the digital thermometer project. The project cost is estimated at $10,000. The total manufacturing cost of the digital thermometer, as called for in the specifications, total $150(that is, $95 parts
