1.In a Venturi meter, (not shown) if the water surface dips a distance of 0.07m, what is the flowrate per width of the channel? The bottom of the meter is also 0.2m above the datum, (where D1=1.2m) giving D2=1.2-0.2-0.07=0.93 m. The density of water = 999 kg/m^3.
2.A level is setup midway between X and Y reads 5.572 ft on X and 4.946 ft. on Y. The level is setup very close to X and a reading of 4.666 ft. is taken on X. what should the reading be at Y to adjust any collimation error of the level?
3.A 2kg moves down a 45 degree incline at a constant velocity of .1m/s. What is the value of the kinetic coefficient of friction between the object and the incline?
