2. A nozzle 3 m long has a diameter of 1.3 m at the upstream end and reduces linearly to
0.45 m diameter at the exit. A constant flow rate of 0.12 m /sec is maintained through
the nozzle. Find the acceleration at the midpoint of the nozzle. Hint: velocity at any
point is equal to the flow rate divided by the area of the pipe at that point. [Ans.
a=0.02579 m/s/s]
3. Water accelerates in an upward sloping pipe at a rate of 1.5 m/s?. The pipe slope is set
at 40 degrees and has a length of 6 m. If the pressure is 63 kPa at section 1, what will be
the pressure at section 2? [Ans. P2=16165.52 Pa]
