I need a clear answer by hand, not by keyboard |dybalaC. Suppose that a certain fraction of the power produced by a 350 MW coal plantis offset by wind power. Assume that when the coal plant runs at its constant ratedpower it has an efficiency of 37%, but that when it needs to be ramped up anddown to compensate for the wind power variations its efficiency is reduced byaccording to e=0.37 -0.00001p², at what p the efficiency is maximum?Signature Head of Department

Please provide equations that you are using so I can follow along and learn how to do this. In Jamestown, NY, a coal power plan consumes coal at a rate of 80 tons/hr. When coal burns, it generates approximately 30,000 kJ for every kg of coal burned. The cooling course for the plant is the nearby Chadakoin River nearby and, by code, the power plant cannot reject more than 13.19 x 109 MJ into the river annually. Determine the maximum average power output of this plant and it's maximum thermal efficiency. To check your work, enter the efficiency, as a decimal, in the box provided.

Differantial Equations
A differential equation encountered in the vibration of beams is d4ydx4=2D where x = distance measured along the beam; [x]=[L] y = displacement of the beam; [y]=[L] = circular frequency of vibration; []=[T1] = mass of the beam per unit length; []=[ML1] D = bending rigidity of beam; [D]=[FL2] Show that the equation is dimensionally homogeneous. Note that [F]=[MLT2] see Eq. (1.21:).
Hello, Please could you answer part (d). a) 0.75 b)26.1798rad/s and same direction as input c)P(out)=1.5kW Im just struggling with part d, thanks
Hi. I am trying to practice this problem using a checker online, but everytime I recalculate my answer it always says it's incorrect. So far I have calculated and tried to input the following values: 59.09kW, 53.0899kW, 21.94kW, and 22.715kW but it always keeps saying they are incorrect. Am I missing a sign change? (Should the answer be negative?) Or am I solving this incorrectly and getting the wrong value each time? Please help show me the correct steps on how to get the correct answer as I am trying to learn this process. Thank you!
