a fountain shoots a stream of water into the air. Roughly where is the center of mass of the water that is in the air at one instant? is the center of mass higher or lower than the middle height.
Center of mass lies below the middle height of fountain because jet deflects outward while rising causing center of mass toward bottom than if left were not deflected making straight jet into the air.

A fountain sends a stream of water straight up into the air to a maximum height of 4.82 m. The effective area of the pipe feeding the fountain is 5.42 x 10-4 m2. Neglecting air resistance and any viscous effects, determine how many gallons per minute are being used by the fountain. (1 gal = 3.79 x 10-3 m3)
A drinking fountain shoots water about 14 cm up in the air from a nozzle of diameter 0.51 cm . The pump at the base of the unit (1.1 m below the nozzle) pushes water into a 1.2 cm diameter supply pipe that goes up to the nozzle.What gauge pressure does the pump have to provide? Ignore the viscosity; your answer will therefore be an underestimate.
A circular pool of water has a fountain in its center, as shown in the figure below. A man measures the circumference C of the pool. He then measures with a protractor the angle of elevation ϕ from the outer edge of the pool (level with the bottom of the fountain) to the top of the fountain's water spout. Find the height from the bottom of the fountain to the top of the water spout. (Use any variable or symbol...
SerPSE10 1 A OP031 MI My A high fountain of water is located at the center of a circular pool as shown in the figure stands at the edge of the pool and uses a protractor to gauge the angle of elevation of the top of the fountain to be below. A student walks around the pool and measures its circumference to be 25.2 m. Next, the student 50.0° How high is the fountain? 10 1 A OP035 My Water...
What is the mass flow rate of water (in lbw/hr) for a 100 lbda/hr air stream at TDB=90°F and TwB=70°F? (round to one decimal place)
1 - A stream of atmospheric air of specific humidity ωa passes through a water spray and comes out with ωb. Under what conditions, if any, would ωb< ωa 2 - State three advantages of the two stroke engine over the four stroke engines. 3 - In a gas mixture, which component will have the higher partial pressure—the one with the higher mole number or the one with the larger molecular weight?

A desiccant is being used to remove water vapor from a stream of air with 90% RH at 50°C. The desiccant is a flat plate with 10.4 and maintains a water activi of 0.04 at the surface exposed to the air stream. The stream of air has velocity of 5m/s moving over the surface in the direction of the 25cm length. The mass diffusivity for water vapor in air is 0.18 x 103 m2/s. Compute the mass flux of water...
A thin stream of water flows smoothly from a faucet and falls straight down. At one point the water is flowing at a speed of v1 = 1.15 m/s the radius of the stream is r1 = 1.00 cm. At a lower position, the radius of the stream is smaller and the velocity is higher because the water is accelerating under gravity. The vertical distance between these two points is 0.144 m. What is the radius of the stream at...
1: A hot-water stream at 95°C enters a mixing chamber where it is mixed with a stream of cold water at 25°C. Assume all the streams are at a pressure of 350 kPa. It is desired that the mixture with a mass flow rate of 0.7 kg/s leaves the chamber at 39°C. Each enthalpy is given by hi hf@95°c = 350 kJ/kg h2 z hr@25°C = 83 kJ/kg h = hf@ 39°C = 175 kJ/kg a. Write down the mass...
A tray tower is designed to absorb acetone from air stream using pure water at 293 K and 101.3 kPa. The inlet air flow rate is 483.33 kg/min (MW air = 29) and it contains 5 mol % of acetone. It is desired to remove 95 % of the acetone from air stream. The equilibrium relationship for this dilute stream is given by the equation of y= 1.186 x. * All the solutions should be presented in the unit of...
