1.Air flows through a horizontal iron tube (e=0.15m) at Q=5.7x10-2 m3/s. find the pipe diameter if the pressure drop is 3.5kPa per 30.5m of pipe. air density = 1.23kh/m3 dynamic vicosity = 1.79 x 10-5 N.s/m2)
2.Given: Vf=Vi + a t and Sf=Si + Vi t + 1/2 a t Cedar points millennium force accelerates from 10 mph to 93 mph in 4.5 seconds. assuming acceleration is constant, find acceleration in ft/sec^2 and distance traveled in meters
3.Given: acceration = -k*sqrt(v) and k is a cosntant when x=0, v=81 m/s, t=0 when x=18 m, v=436 m/s determine: a) velocity of particle when x=20 m b) the time required for the particle to come to rest
4.Car moving 54 km/h when light is 240 m away turns red. Light stays red for 24 seconds. If the motorist wishes to pass the light just as it turns green without having to stop, what is the required uniform deceleration of the car and what is the speed of the car as it passes the light?
A film of newtonian liquid folws down the outside surface of avertical cylinder of radius R. the flow is steady, laminar andthe thickness of the film is constant.
An ethanol plant distills alcohol from corn. The distiller processes 2.0 t/h of feed containing 15% alcohol and 82% water; the rest is inert material. The bottoms (waste) produced is 85% of feed and contains 94% water, 3.5% alcohol, and 2.5% inert..
The temperature in the stack is 350 degrees F and the pressure is 725 mm Hg. If the total flow rate of gas out of the stack is 200 standard cubic meters per second, calculate the total mass emissions of particulates out of the stack in kg/day.
Natural gas is stored in a spherical tank at a temp. of10oC. At a given initial time, the pressure in thetank is 100 kPa gage, and the atmospheric pressure is 100 kPaabsolute
Determine the unfactored dead load and live load on a typical interior roof beam, sketch the loading on the beam, and draw the shear and moment diagrams for the beam assuming the beam is simply-supported.
A section of highway is 18 km long. A bus going fromeast to west on this road climbs for 6 minutes at one speed, levelsoff for 6 minutes at a second speed and descends for 6 minutes at athird speed. Going from west to east on the same section ofthe r..
Plot the distribution of vertical effective stress and porewater pressure with depth if the void ratio of the sand is 0.6 and the degree of saturation is 90%. Neglect pore air pressure
You will be using a large crane... lets say one with a capacity of 30T. What considerations need to be made prior to picking up a 15T load with the crane? If you are familiar with the use of a crane be sure to include the discussion of the outriggers..
you are working as a project analyst for the local gas utility and you have been placed on a project to install an
Calculate the BOD loading and days of winter storage available between the 0.6 and 1.5 m depths, assuming a daily water loss of 0.30 cm by evaporation and seepage.
For each subcritcal, critcal, and supercritcal flows, comment on the values for the Froude number, the depth of the water channel, and the specific energy. How do these values compare to each other for each of the flow types
an air space above a long tube is pressurized to 50 kPa vacuum. water (20 degrees C) from a reservoir fills the tube to a height h. If the pressure in the air space is changed to 25kPa vacuum, will h increase or decrease and by how much
