Blending of wastes to achieve an optimum C/N ratio. Leaves, with a C/N ratio of 50, are to be blended with waste-activated sludge from a wastewater treatment plant, with a C/N ratio of 6.3. Determine the proportions of each component to achieve a blended C/N ratio of 25. Assume that the following conditions apply: moisture content of sludge = 75%; moisture content of leaves = 50%; nitrogen content of sludge = 5.6%; and nitrogen content of leaves = 0.7%.

Steam enters an adiabatic turbine steadily at 3 MPa and 400°C and leaves at 50 kPa. If the isentropic efficiency of the turbine is 66.7%, determine the actual temperature of steam at turbine exit. The mass flow rate of the steam flowing through the turbine is 218 kg/min, determine the power output from the turbine. Plot the T-s diagram.

In the Bohr model, when an electron leaves one n orbit and enters another n orbit, a photon is either emitted or absorbed. Derive a relationship between the wavelength of the emitted or absorbed photon and the change in the DeBroglie wavelength of the electron when it moves from one n to another n.

There are two ways for finding the benefit to cost ratio (B/C Ratio) B/C Ratio = [ Annual Benefits-Annual Disbenefits] / [Annual Cost of Implementing Project] B/C Ratio = [NPV of Benefits-NPV of Disbenefits] / [NPV of Implementing Project] If the B/C Ratio is greater than one, we can infer that the project is worth undertaking. Note that there can only be one B/C ratio for a project (unlike IRR which can at times have multiple values) Problem: The City...

A sweet, water-saturated natural gas enters a compressor at 50 psia and 100F and leaves at 200 psia and 300F. a. Is there any chance of water condensing in the compressor? If so, how much? Answer in lb H2O/MMscf gas compressed. b. Estimate the mole fraction of water vapor in the gas stream leaving the compressor. c. The natural gas is then cooled to 190 psia and 100F before entering the second stge of compression. Should a vapor-liquid scrubber be...

I am making a working reagent that requires a 50:1 ratio (50 of reagent A and 1 of reagent B) and a total volume of 600uL. Therefore, I need 588uL of reagent A (water) and 12uL of reagent B (lead acetate). I need to make a solution of lead acetate (reagentB) with: 3mM,7.7mM, and 46mM. Upon calculating the mass needed to make 3mM, 7.7mM, and 46mM I got: 0.9756 mg, 2.504 mg, and 14.9592 mg respectively and to each mass...
