The Centralia power plant emits SO2 at the rate of 150 g/s. It has an effective stack height of 50 m. Surface winds at 10 m are steady at 2.5 m/s and it is a fall afternoon.
a) Calculate the ground level SO2 concentration in ug / m3 at a point 4 km downwind and 0.1 km in the cross wind direction.
b) What is the maximum downwind concentration and at what distance does this occur?
c) There is a town with an SO2 monitor 20 km downwind of the power plant. How large can Q in g/s be if SO2 concentrations are to be kept below 365 ug/m3 for the conditions listed
A diffraction grating used at normal incidence provides a spectral line of certain order with wavelength 6000A 0 superimpose on another spectral line of wave length 5000A 0 of th
Explain why a narrow slit is used in case of Bi-prism experiment where as an extended source is used in Newton's rings experiment?
Watt; W (after J. Watt, 1736-1819): The derived SI unit of power, explained as a power of 1 J acting onto a period of 1 s; thus it has units of J/s.
Give two basic important characteristics of nuclear forces? Neutrons are the best projectiles of process of nuclear reactions. Why? Give any two properties of neutron.
In this case both source and screen are effectively at infinite distance from the diffracting device. Basic types: Diffraction at single slit, double slit and diffracting gratin
describe the applications of potentiometers
What is the echo of the launched pulse? Any discontinuity into the medium of propagation of an ultrasonic pulse provides rise to back-reflection that travels back to the input
How many times the kinetic energy reach at minimum and maximum point during one oscillation?
Angle of Minimum Deviation: The angle of deviation has least value when incident ray and emergent ray make equivalent angle with the normal. The value of angle of deviation is
