Water enters a horizontal pipe of non-uniform cross-section with a velocity of 2 m/s and leaves the other with a velocity of 10 m/s as shown in the figure below. The pressure at the first end Is P, = 1000 kPa. What is the pressure at the
other end?
P.
Vi = 2 m/s
v2 = 10 m/s​

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
