A stack was sampled for 8 minutes. The gas velocity (at stack conditions) through the sampler was 15.0 m/s and the area of the sample probe was 5.07 square cm. The net mass of particulates collected was 0.430 grams.
a. Calculate the concentration of particulates in the stack in micrograms per cubic meter.
b. The temperature in the stack is 300 degrees F and the pressure is 725 mm Hg. If the total flow rate of gas out of the stack is 190 standard cubic meters per second, calculate the total mass emissions of particulates out of the stack in kg/day.
A 20-kg iron ball is moving at 100 km/hr should be accelerated at a constant rate of 10 m/(sec)^2. What is the force required
Calculate the mass of the green house gas and ozone depleting substance CFC-11 (chemical Formula = CCl3F) in the atmosphere. Use units of GtC (giga tonnes carbon). Production of this substance is now banned and mixing ratios are slowly decreasing wit..
You are asked to design a pump station to conveywaste water at a flow rate of 250 cubic meters per hour to anequalization tank. A velocity of at least 3ft/s must be maintained in the pipe to prevent deposition and provide scouring of any previously d..
The motion of a particle is defined as x=t^2-8t+7 and y=0.5t^2+2t+4, where x and y are in meters and t is in seconds. Determine the magnitude of the smallest velocity reached by the particle, and the time, position, and direction of that velocity.
A horizontal water jet impinges against a vertical flat plate at 25 ft/s and splashes off the sides in the vertical plane. If a horizontal force of 350 lbf is required to hold the plate against the water stream,
What percentage removal should be expected for each of the following particle settling velocities in an ideal sedimentation tank: 0.1 mm/s, 0.2 mm/s, 1 mm/s.
Clay was extracted from a soil sampling tube to form a cylindrical sample 100 mm in diameter and 100mm in length.the sample was weighed in its natrual moist state and found to have a total mass of 1531g
How do you find the force ratio equation to determine the maximum total load that can be applied to a truss?
A stabilization pond is designed for a 35-day detention time. If the pond is maintained at a capacity of 40 acre-feet, what is theaverage gpd flow to the stabilizaiton pond?
(a) determine if the flow will choke and both the downstream and upstream water depths. (b) if there is also a 1 ft high step up in bottom elevation at the contraction, determine if the flow will choke and both the downstream and upstream water de..
Fluid mechanics ch.9: A supertanker has length, breath, and draught (fully loaded) dimensions of 325m, 48m, and19m, respectively. In open seas the tanker normally operates at a speed of 115 kt (1 kt=0.515m/s).
