for the pipe
volume flow rate = Area * velocity
volume flow rate = 15 *10^-4 * 3 m^3/s
let the time taken to fill the barrel is t
total volume = volume flow rate * t
2.2 = 15 *10^-4 * 3 * t
solving for t
t = 488.9 s
t = 8.15 min
the time taken to fill the barrel is 8.15 min

Q22 An oil tanker is being filled with oil at a rate of roughly 170 – 190 Litres/minute. The oil comes from a vertical, cylindrical vessel (at atmospheric pressure) with 8 metres diameter. A flow meter can be used to measure the actual filling rate. Manufacturer data shows that the flow meter is 95% accurate when measuring flow rate between 150 – 200 litres/minute. A level gauge can be used to measure the amount of oil being drained from the...

Maria is filling a bucket of water from a faucet. After she turns it on, she sees that the cross-sectional area of the water stream right below the faucet is about the size of a quarter, or 4.62×10^4 m2. The stream constricts to about the size of a dime, or 2.52×10^4 m2, after falling 2.50 cm. If the bucket Maria is filling has a volume of 10.0 L, how long will it take to fill the bucket?

Maria is filling a bucket of water from a faucet. After she turns it on, she sees that the cross-sectional area of the water stream right below the faucet is about the size of a quarter, or 4.62×10^−4 m^2. The stream constricts to about the size of a dime, or 2.52×10^−4 m^2, after falling 2.50 cm. If the bucket Maria is filling has a volume of 10.0 L, how long will it take to fill the bucket?
