For the hose:
dV/dt = pi*R^2*v
v = 2.5 m/s = 250 cm/s
r = d/2 = 2.2/2 = 1.1
dV/dt = pi*(1.1)^2*250 = 950 cm^3/s

Gardener: Basic garden tools

-- A flat-tip spade cuts mellow, straight slices. It's perfect for making a clean line while edging beds or tidying up lawns around walkways and fences. The D-finger and shorter shaft help lift heavy loads and keep your assemblage properly aligned.
