Please answer all parts of the question.

Answer 1

here,

r1 = 0.22 cm = 0.0022 m

r2 = 0.85 cm = 0.0085 m

volume flow rate , V = 0.45 L/s

V = 4.5 * 10^-4 m^3 /s

a)

let the speed of water be v2

V = pi * r2^2 * v2

4.5 * 10^-4 = pi * 0.0085^2 * v2

v2 = 1.98 m/s

the maximum height , h2 = v2^2 /( 2g)

h2 = 1.98^2 /(2 * 9.81) m

h2 = 0.2 m

b)

let the speed of water be v1

V = pi * r1^2 * v1

4.5 * 10^-4 = pi * 0.0022^2 * v1

v1 = 29.6 m/s

the maximum height , h1 = v1^2 /( 2g)

h1 = 29.6^2 /(2 * 9.81) m

h1 = 44.7 m
