A 2L bottle is filled with water and has a 2mm diameter hole in the side 2cm from the bottom and the top is open to the atmosphere. a) What is the velocity of the water stream coming out of the hole when the water is 10cm above the hole? Treat the water as an ideal fluid obeying Bernoulli's equation. Additionally, you may assume that the flow is slow enough that the velocity of the water at the top surface...

5.6 A 7.5 cm diameter jet of water is directed at a hole in a vertically supported plate Some of the water spreads as a film over the surface of the plate and the remainder leaves horizontally through the hole. The angle between the jet and the plate is 65° and the velocity within the jet is uniform and 10 m/s. Assume inviscid flow and neglect gravity forces. The density of water is 1000 kg/m a) What is the velocity...

6. (25 points) Water at standard atmospheric conditions flows through a 100 m long plastic pipe with a circular cross section of diameter D = 0.2 m at an average velocity of 10 cm/s. The flow exits into the atmosphere. The pipe material is smooth and has essentially no roughness. What is the pressure at the pipe entrance if it is horizontal? What is the pressure at the pipe entrance if the elevation increases by 50 cm? A Moody diagram...

In-class problem (submit by 5 pm) Water at a gauge pressure of 3.8 atm at street level flows into an office building at a speed of 0.06 m/s through a pipe 5.0 cm in diameter. The pipes taper down to 2.6 cm in diameter by the top floor, 20 m above. Calculate the flow velocity and the gauge pressure in such a pipe on the top floor. Assume no branch pipe an ignore viscosity.
