V1 =0.5 m/s
The flow entering the container in a 5 cm diameter pipe has 0.5 m/s uniform velocity. Water is
supplied steadily from the top surface of the container with a volume flow rate 0.001 m³/s. Flow
exits the container in a 10 cm diameter pipe with a non-uniform velocity distribution, which is:
V =
wherer, =
Assume a steady incompressible flow where water level in the container remains the same.
a) Determine the water volume flow rate leaving the container
b) Determine the maximum velocity (Vmax)
External Problem 2: Linear Momentum and Bernoulli Equations
The double nozzle in the figure below discharges water at A and B into the atmosphere at a rate
of 0.5 m'/s. The nozzle is lying in a horizontal plane.
Assume steady and frictionless flow and the water speed in each jet (A and B) to be the same.
Jet A is 10 cm in diameter, jet B is 12 cm in diameter, and the pipe inlet is 30 cm in diameter. (p
- 1000 kg/m').
a) Applying Bernoulli's equation between the inlet section and any of the outlet sections,
show that the pressure at section 1 is 315 612 Pa gage;
b) What force acting through the flange bolt is required to hold the nozzle in place?
