Water flows at along a channel which is open to the atmosphere all along its length. The initial width of the channel is 4.3 cm and the initial depth of the water is 3.4 cm. The channel width then reduces to 3.4 cm and the depth of the accelerated water flow to 1.6 cm. Take 'g' as 9.807 m/s?. a) Assuming that energy is conserved, calculate the flow rate through the channel, in litres/sec to 3.5.1. Number b) State the initial velocity, in cm/s to 3.s.f. Number c) Taking the density of water as 1000 kg/m?, state the increase in dynamic pressure across the contraction, in Pa to 3.s.f. Number
