A new coal-fired power plant burns 50,000 tons/day of coal with 7% ash and a heating value of 12000 Btu/lbm. Forty percent of the ash drops out of the furnace as slag. Calculate the efficiency required of an ESP to remove fly ash if the plant is to meet the NSPS for particulates.
There are four stable isotopes of iron with mass numbers 54, 56, 57, and 58. There are also two radioactive isotopes: iron-53 and iron- 59. Predict modes of decay for these two isotopes. (See Table 18.2.).
Before developing the dead-weight gauge, he worked in a mine shaft, and used a mercury manometer for measurements of pressure to more than 400 bar. Estimate the height of manometer required.
a. What alarms would you add to the vaporizer control scheme shown in Figure? Indicate whether the alarm would signal high or low conditions, what the alarm would signify, and what operator response would be required in each case.
Is carbon dating more appropriate to measure the age of materials that are a few years old, or a few thousand years old or a few million years old?
If nitrogen at 150o C flows past one section of the tube at a velocity of 2.5 m s-1, what is its temperature at another section where its velocity is 50 m s-1? Let CP = (7/2)R.[148.80 C]
Explain whether the following circuit allows the investigator to conduct a voltage clamp experiment. The unmyelinated axon is sealed at both ends. A silver wire is inserted inside the axon that eliminates Ra. Clearly state any assumptions.
A process for sulfonation of phenol requires the use of a 3000-gal storage vessel. It is desired to determine the most suitable material of construction for this vessel. The time value of money is to be taken into account by use of an interest rat..
A turbine is fitted in the pipeline to recover the excess energy that is available, over that required to transfer the liquid from one vessel to the other. Estimate the power that can be taken from the turbine, when the liquid transfer rate is 500..
the reaction rates of all the elementary reactions of type (ii) in a weakly realistic mechanism are linear functions of all the concentrations separately.
Prepare a PowerPoint presentation to provide an argument for or against the use of glass over PET/PEN for small-pack beer packaging.
Materials Properties, Consider the following three engineering materials: (i) low-carbon steel; (ii) alumina; (iii) glass-fiber reinforced polymer.
