1.Determine the settling rate of fly ash particles entering the smokestack of a municipal incinerator. Average particle size has been found to be 5.0 µm and the temperature of the stack exhaust gases is 750 oC. Confirm your analysis
2.Show that the Mach number is proportional to the square root of the ratio of the inertial force to the elastic force.
Hint: The elastic force involves the bulk modulus E
3.The flowrate Q over a rectangular sharp crested weir depends on the width of the notch b, the head on the weir H, and the acceleration due to gravity g.
Find how many dimensionless parameters govern this problem. Use dimensional analysis to find the relationship.
A trapezoidal river channel section has a base dimension of 30 feet, a liquid depth of 4 feet, and side slopes of 4 to 1 (horizontal to vertical).
how to design a simply supported rectangular concrete beam having cross section of 20 mm by 40 mm and a length of 3 meters that couldcarry a uniform load of 1000 KN
A particle moving along a straight line is subjectd to a deceleration a=(-2v^3)m/s^2 where v is in m/s. If it has a velocity v=8 m/s when t=0, determine its velocity when t=4s.
Write a program that uses menu to select a type of figure (triangle, sqaure, pentagon, hexagon, heptagon, octagon), and then use switch-case to determine the value of n.
Hydrogen sulfide (H2S) is an odorous gas that can be stripped from solution by gas stripping. The efficiency of the process will strongly depend on the pH of the solution. The equilibrium reaction is: in a pocess similar to ammonia.
An ocean outfall diffuser that discharges treated wastewater into the Pacific Ocean is 500m from a public beach. The wastewater contains 105 coliform bacteria per milliliter. The wastewater discharge flow rate is 0.3 m3/s.
the circular top of a can has a radius of .0320m. the pull-tab has an area of 3.8x10^-4 m^2. the absolute pressure of the carbon dioxide in the can is 1.40x10^5Pa. find the force that these gas generates on the top of a can?
the 3.5mg engine is suspended from a 500 kg spreader beam and hoisted by a crane which gives it an acceleration of 4m/s^2 when it has a velocity of 2m/s. determine the force in chains AC and AD during the lift.
How do you calculate the force of water hitting a concrete cylindrical pole. The velocity of the water is 2 ft/s, the depth of the water is 10 ft, and diameter of the pole is 3 ft. So what would be the total force exerted on the pole by the water?
A tidal channel, which may be assumed to be rectangular, is 40 m wide and conveys a discharge of 60 m3/s at a depth of 1.52 m. A tidal bore is seen to propagate upstream with a wave speed of 5 m/s.
The wheel of radius r rolls without slipping and has an angular velocity w. Write an expression for the velocity of point A in terms of theta and show that the velocities of A and B are perpendicular to one another
Presedimentation can reduce the suspended solids concentration of raw river water from 500 mg/L to 200 mg/L. How many pounds of dry solids does this represent per million gallons?
