One end of a cylindrical pipe has a radius of 2.2 cm. Water (density = 1.0 × 10³ kg/m³) streams steadily out at 9.5 m/s. At what rate is water mass leaving the pipe?

Suppose you spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.461×10−3 m3/sand the diameter of the nozzle you hold is 5.67×10−3 m. At what speed ? does the water exit the nozzle?

Problem 1: A large weather balloon has a volume of 2000 m3 and a total weight of 800 N is filled with gas. The basket attached to the balloon has a weight of 1200 N and inside the basket there is a total mass M. The balloon starts from rest an ascends a total distance of 25 meters in 5 seconds. If the density of air is 1.20 kg/m3 and the average density of gas is 0.179 kg/m3, what is the value of the mass M in kg. Hint: the system has an acceleration Show a coordinate system and a free body diagram.

Hot water with a density of 980 kg/m3 flows through a 53.4 mm diameter round pipe at 1.91 m/s.  What is the mass flow rate (in kg/s) of the water [round your final answer to 2 decimal places] {Acircle = (π/4)d2}

A round pipe of varying diameter carries petroleum from a wellhead to a refinery. At the wellhead the pipe\'s diameter is 58.5 cm and the flow speed of the petroleum is 13.9 m/s. At the refinery the petroleum flows at 6.53 m/s. What is the volume flow (m^3/s) rate of the petroleum along the pipe and what is the pipe\'s diameter (cm) at the refinery?

Air is evacuated from a vacuum chamber and the flow rate is measured. A section of circular plumbing is removed and replaced with a piece having a radius that is half the size of the original. The flow rate is measured again. What is the ratio of the new flow rate to the old flow rate?

Suppose you spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.613 × 10-3 m³/s and the diameter of the nozzle you hold is 5.13 × 10-3 m. At what speed v does the water exit the nozzle? V = m/s

A large pipe with a radius of 50 cm has oil flowing through in at 1.5 m/s. The pipe narrows into a narrower tube with a raduis of 10 cm. what is the speed of the oil flowing through the smaller pipe? 1. 0.375 m/s 2. 3.75 m/s 3. 37.5m/s 4. 0.25 m/s 5. none

A garden hose of inner radius 1.00 cm carries water at 1.41 m/s. The nozzle at the end has inner radius 0.200 cm. How fast does the water move through the nozzle?

Suppose you spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.573×10−3 m3/sand the diameter of the nozzle you hold is 5.41×10−3 m. At what speed ? does the water exit the nozzle?
