Wаter flоws thrоugh а hоrizontаl pipe. In the first section, the pipe has a cross-sectional area of 0.080 m², the water's speed is 3.00 m/s, and the pressure is 400 000 Pa. The pipe then narrows to a cross-sectional area of 0.020 m². Assuming the density of water is 1 000 kg/m³, what is the water pressure in the narrow section of the pipe? Hint: Find the speed of the water in the narrow section of the pipe first.
