Water flows at a rate of 800 cm3/min in a pipe of varying cross-sectional areas. Calculate the velocity of the water at the section where: (a) the radius is 3.0 cm; and (b) the radius is 5.0 cm

A coin that is tossed straight up into the air. After it is released, it moves upward, reaches its highest point and falls back down again. Use one of the following choices (A through G) to indicate the acceleration of the coin during each of the stages of the coin's motion described below. Take up to be the positive direction. Answer choice J if you think that none is correct. A. The acceleration is in the negative direction and constant. B. The acceleration is in the negative direction and increasing. C. The acceleration is in the negative direction and decreasing. D. The acceleration is zero. E. The acceleration is in the positive direction and constant. F. The acceleration is in the positive direction and increasing. G. The acceleration is in the positive direction and decreasing. The coin is moving downward. A OF ΟΕ B

1 - f) What is the velocity of the water at point ONE? (Assume the V2 = 16.6 ft/s and the diameter of the pipe at points one and two is 12 in and 18 in, respectively.) PS: Approx value requested. 40 ft/s 150 ft/s 300 ft/s 100 ft/s 10 ft/s 3 ft/s Fluid flow - 3

A man attaches a divider to an outdoor faucet so that water flows through a single pipe of radius 9.25 mm into four pipes, each with a radius of 5.60 mm. If water flows through the single pipe at 1.45 m/s, calculate the speed (in m/s) of the water in the narrower pipes. HINT |m/s Need Help? Read It Watch It

If a kitchen sink has a volume of 20 L. Water flows in the sink with a mass flow rate of 0.5 kg/s. If the drain is closed, how long, in seconds, does it take for the sink to fill up?  Density of water = 1000 kg/m3

Find the speed of water at the narrow end of a pipe through a cross section of0.01 m2 when water flows from the other end of area 0.02 m2 at a flow speed of15 m/sec?

At one point in a pipeline the water's speed is 3.00 m/s and the gauge pressure is 5.00×104 Pa. Find the gauge pressure at a second point in the line, 11.0 m lower than the first, if the pipe diameter at the second point is twice that at the first.

An oil tank is shaped like a right circular cylinder of diameter 4 ft. Find the total fluid force against one end when the axis is horizontal and the tank is half filled with oil of weight density 50 lb/ft³.

(a) At one point in a pipeline the water’s speed is 3.00 m/s and the gauge pressure is 5.00∙104 Pa. Find the gauge pressure at a second point in the line, 11.0 m lower than the first, if the pipe diameter at the second point is twice that at the first.  Note: density of water is 1000 kg/m3. (b) If the gauge pressure at the second point is half of what you found in part (a), calculate how much energy was lost to friction.
