The figure above shows a section of a long tube that narrows near its open end to a diameter of 1.4 mm. Water at 20∘C flows out of the open end at 0.020 L/s.
What is the gauge pressure at point P, where the diameter is 4.4 mm? The viscosity of water is 1.0×10−3 Pa⋅s.
The correct answer is 3.0×105 Pa. Can someone show the work?

2- Water in the bottom of a narrow metal tube is held at a constant temperature of 303 K. The total pressure of air (assumed dry) is 1.01325 x 105 Pa (1.0 atm) and the temperature is 303 K. Water evaporates and diffuses through the air in the tube and the diffusion path (z2 - z1) is 0.2 m long. The tube diameter is 10 mm. The vapor pressure of water vapors at 303 K is 4242 Pa. The experimental...
