1.There are two .25 m long concentric cylinders in a viscometer. Only the inner cylinder is rotating. THe velocity distribution is given by V(r)=1000r-0.4/r [m/s]. If the diameters of the cylinders are 3 cm and 5 cm, respectively, what is the fluid viscosity if the torque on the inner cylinder is measured to be 0.0026 Nm?
2.A student in the laboratory plans to exert a vacuum in the head space above a surface of water in a closed tank. She plans for the the absolute pressure in the tank to be 10,400 Pa. The temperature in the lab is 20°C. Will water bubble into the vapor phase under these circumstances?
Draw the shear and bending moment diagrams for the beam AB, and determine the maximum absolute values of the shear and bending moment.
Prove clausius inequality in steam power plant operating in cycle.given that heat transfer in boiler =2070kJ/kg at 164 degree celcius ;heat tranfer in condenser =1905 kJ/kgat 52 degree celcius.
A square footing 2 meters by 2 meters is to be constructed 1.22 meters below the ground surface. The groundwater table is located 1.82 meters below the ground surface.
How many cubic yards of aggregate must be ordered for a road base 16 inches thick and 2000 feet long with a top width of 30 ft, if the side slopes are one on one, or 45 degree?
A 40lb, .8ft diameter, 1ft tall cylindrical tank slides slowly down a ramp with a constant speed of .1ft/s. The uniform-thicknessoil layer on the ramp has a viscosity of .2lb*s/ft^2.
Determine the surface area of a primary settling tank sized to be handle a maximum hourly flow of 0.570 m3/s at an overflow rate of 60 m/day.If the effective tank depth is 3.0 m,what is the effective theoretical detention time?
A 780-g mass is attached to a vertical spring and lowered slowly until the mass rests at its equilibrium position 30 cm below the original length of the spring. It is then set into simple harmonic motion of amplitude 5 cm.
Your engineering consulting firm has been asked to determine the specific weight of an unknown material. You decide to use the concept of buoyancy to figure this out. So you weigh the material in both air and water.
Determine the corresponding error in the computed discharge
Imagine two small towns of 1,000 people: Blacktop and Parktown. In the urban sprawl that is Blacktop, all the residents own fuel-efficient cars (15 km/liter) and travel an average of 20,000 km per year.
What is the highest downward speed (the terminal velocity), in miles per hour, ? At the terminal velocity the downward force (the weight) is equal to the upward force (the aerodynamic drag force).
emissions from waste oil combustion may be estimated using ap-42 1.11. A small boler is operated from 10/15/2012 through 4/15/2013 and it is used to burn 45 gallons per hour of a blended waste oil having an ash content of 7%
