1.How can the water pressure in a pipe be measured simply?2.What force causes the water pressure to fall as it flows along a pipe?3.How do you think the pressure drop will change when each of the three variables changes (the length of the pipe L, The diameter of the pipe D, and The flowrate Q)?4.What units will you measure flowrate in? How can you convert your measurements so that they are in SI units?
The rigid bar of negligible weight is supported as shown. Find the stress in each rod if the temperature rises DeltaT after a load P is applied. Use the following data: area of steal rod 320mm2, bronze rod 1300mm2, thermal expansion coefficient Al..
Compute the volume of a waste sludge with 96% water content containing 1000 lb of dry solids. If the moisture content is reduced to 92%, what is the sludge volume
A field sample of medium sand with median grain size of 0.84 mm will be tested to determine the hydraulic conductivity using a constant-head permeameter. The sample has the length of 30 cm and a diameter of 5 cm.
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?
A fixed-bed carbon adsorption system consisting of two 3-foot-deep beds containing 6 x 16 mesh carbon operates at a superficial gas velocity of 60 ft/min. Specify the horsepwoer of the fan motor for 15,000-cfm system
If the front edge of a contaminant plume is perfectly straight, how long would it take to travel to Well 1 after first arriving (simultaneously) at Wells 2 and 3, assuming that the contaminant plume travels only half as fast as the groundwater flo..
How much (in addition to your trade-in value) can you afford to spend for a car averaging 30 mpg You expect to drive 15,000 mile/year and expect gasoline to cost $4.00/gallon and you will keep he car 10 years. Your personal interest rate is 6%/yea..
Consider again the proposed water treatment plant for a city of 100,000 people where the maximum daily water usage rate is 99 X 106 L/d. Determine (a) the number of kilograms of chlorine needed per day and (b) the capacity of the contact tank.
A bar of monel metal (length L=9 in., diameter d=0.225 in.) is loaded axially by a tensile force P. If the bar elongates by 0.0195 in., what is the decrease in diameter d What is the magnitude of the load P
A paddle wheel, inserted inserted into the volume, does 720 KJ of work on the air. If the volume is 2 cubic meters, calculate the entropy increase assuming constant specific heats.
if a clay slope at a construction site fails derive an equation for the undrained shear strength of the clay given that the shear reistance along L of the slope can be given as: (SuH0)/ sin beta
The uniform steel shaft has two gears attached to it at B and C, two frictionless bearings, and the motor. The motor generates 15kip·in and the gears consume 10kip·in and 5kip·in. Find the diameter of the shaft if the maximum rotation between A an..
