A stack (T=550*F and P=750mm Hg) was sampled using EPA Method 5. The total gas volume that flowed through the dry gas meter was 2.785 cubic meters (at T=60*F and P=800mm Hg). The mass of particles collected was 1.50g. Also, 72.0g of H2O was collected in the impingers.
A. Calculate the concentration of PM in the stack (micrometers/m^3) at stack conditions
B. The stack gas exits at an average velocity of 20m/s, and the stack has an inside diame of 5m. What is the emission rate of PM, in kg/day?
C. What is the PM concentration in micrograms/dscm?
Vehicles arrive at the booth at a rate of 4 vehicles per minute. The attendent opens the booth and improves the service rate over time following the function u(t)= 1.1 +0.3t, where u(t) is in vehicles per minute and t is in minutes.
The rod has a uniform cross-section of 53mm2. The external load consists of point loads: two P1 of 3kN, two P2 of 1kN, and one P3 of 7kN. What is the normal stress at the fixed support
The design discharge is 9.5 m^3/sec and the inlet will be submerged but not the outlet. Determine the depth that will result upstream (above the invert) during the design flood event.
A room has 10 cotton spinning looms. Once the looms are set up, they run automatically. The setup time is exponentially distributed, with mean 10 minutes. The machines run for an average of 40 minutes, also exponentially distributed.
You open a 16 oz (1 pint) bottle of a carbonated soft drink that has a temperature of 5°C, then you get distracted and forget to drink it. You come back quite some time later and find that it has gone "flat," and that it has gotten warm (20°C).
A 25 mm diameter steel cylinder falls under its own weight at a uniform rate of 0.1 m/s inside a tube of slightly larger diameter. Castor oil of viscosity 0.25 N.s/m2 fills the spacing between the tube and the cylinder.
Oil (specific gravity 0.752) flows through a 6" horizontal pipe under a pressure of 60 psi. Assuming no losses, what is the flow in cfs if the pressure at a 3" diameter reduction is 20 psi
Crude oil at 20 degrees C fills the space between 2 concentric cylinders 250mm high with diameter of 150 and 156mm. What torque is required to rotate the inner cylinder at 12 rev/min
a bourdon pressure gauge attached to the outside of a tank containing air reads 77.0 psi when the local atmospheric pressure is 760 mm Hg. what will be the gage reading if the atmospheric pressure increases to 773 mm Hg
a buried horizontal concrete pipe (n=0.012) of unknown length needs to be replaces. the length is not known because the original plans for the pipeline route have been lost. the pressure head drop along the segment that needs to be replaced is 29...
A fully enclosed cylindrical fuel tank with a diameter of 6.00 meters and a height of 8.00 meters has a manufacturing tolerance of +/- 0.04 meteres for each of these dimensions.
After injecting 50 MMSCF (14.7 psia and 60 oF), the pressure increase from 2500 to 3500 psia. Deviation factors for the gas are 0.90 at 3500 and 0.80 at 2500 psia and the bottom-hole temperature is 160 oF. What is the cubic feet of gas storage spa..
