Water flows through a 7cm pipe at the rate of 4m/s.how many cm³ of water flow through the pipe in one second
Diameter of pipe is D = 7 cm.
Cross sectional area of pipe is A= pi.(D^2)/4 cm^2
A = pi*49/4 = 38.48 cm^2
Water flows at v = 4 m/s
Water flow rate is Q = Av = 38.48 * 4 = 153.94 cm*3/s
Q = 154 cm^3/s = 154 * 10^(-3) litres/s = 0.154 litre/min
Q = 0.154 l/s
