1.In a venturi meter the gage pressure is 120 kPa whencavitation just starts to occur. If the Diameter is 40 cm and theneck diameter is 14 cm, what is the water discharge in the systemfor this condition of incipient cavitation?
Atmospheric pressure is 100 kPa gage, and water temperature is10 degrees C.
2.The slope distances shown were measured with an EDM while the differences in elevation between the ends of each line were determined by leveling. What are the horizontal distances?
Slope Distance(ft)
a. 1310.81
b. 792.22
c. 656.72
Elevation Difference
a. -36.96
b. -17.03
c. 13.44
3.A motorcycle is 125 kg and a center of mass at G1, while the rider is 75 kg and has a center of mass G2. If the coefficient ofstatic friction between the wheels and the pavement is Us=.8;determine if it is possible for the rider to do a "wheely", i.e.,lift the front wheel off the ground. What acceleration is necessaryto do this? Neglect the mass of the wheels and ssume that the front wheel is free to roll. all necessary distances are given.
