water flows at the rate of 40ml/sec through an opening at the bottom of a large tank in which the water is 5.0 meter deep. the initial pressure on the surface of the water is atmosphere pressure. calculate the flow rate out of the tank at the opening if an additional pressure of 50kPa is applied to the top of the water tank. apply Bernoulli's equation (twice) in solving this problem, once before, and once after the additional pressure is added to the surface. assume (due to the large volume of the tank) that the water velocity at the surface is essentially zero in both cases. flow rate should be expressed in units of m^3/sec

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...

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...

If a person drinks a large amount of water very quickly, it is possible to exceed the rate of water removal by the kidney (~1 L/hour), essentially diluting the blood. The resulting osmotic pressure causes cells to swell. Fat and muscle cells have a capacity to adjust to this change in volume, but neurons in the brain do not have room to accommodate this size increase. (The skull is so densely packed, there is no room for swelling!) Consequently, as...
