Wаter flоws thrоugh а hоrizontаl pipe. The pipe has a cross-sectional area of 0.040 m² at point A and 0.020 m² at point B. At point A the water velocity is 3.0 m/s. (a) Calculate the velocity of the water at point B.(b) According to Bernoulli’s principle, would the pressure at B be greater than, less than, or equal to the pressure at A?
