Q. Water is pumped into a storage tank from a well delivering 17 gallons of water in 33 seconds throughout a pipe of 1.0 in 0.2 cross-sectional area. What is the average velocity of the water in the pipe as the water is pumped from the well?
A tank having a volume of 0.10 m3 contains helium gas at 155 atm. How many balloons can the tank blow up if each filled balloon is a sphere 0.30 -m in diameter at an absolute pressure of 1.3 atm.
A projectile is fired at time t = 0.0 s, from point 0 at edge of a cliff, with initial velocity components of vix=30m/s and viy = 100m/s. The projectile rises, and then falls into the sea at point P. The time of flight of the projectile is 20s.
