How many liters pass through the hose in 25.0 min? water flows through a 13.0cm diameter fire hose at a rate of 4.53 m/s. a. What is the rate of flow through the hose in Lmin? B. How many liters pass through the hose in 25.0 min? water flows through a 13.0cm diameter fire hose at a rate of 4.53 m/s. a. What is the rate of flow through the hose in Lmin? B. How many liters pass through the hose in 25.0 min?

Explanation / Answer

water flow = speed * Area

area = pi * r^2 = r = 6.5 cm

speed = 4.53 m/s = 453 cm/s

water flow = 60127.7272 cm^3/s

1cm^3/s = 0.060 Liters per minute (L/min)

water flow = 3607.66 L/min

part b )

in 1 min 3607.66 L is flowing

in 25 min = 25 * 3607.66

= 90191.5 L
