Solve the following problem below. Show step by step process in calculation for verification and authentication of your solution: The Venturimeter shown in the diagram is a device used to measure the speed of a fluid in a pipe. The cross-sectional areas at points A and B are 10 cm and 5 cm. The height difference of the water levels in the two tubes are 61.2 cm. a.) What is the speed of the water at point A? b.) Calculate flow speed at point B c.) What is the pressure difference between points A and B in kPa? d.) If the pressure at point A is 15,000 Pa, what is the pressure at point B? 61.2 cm VA PA A 10 cm B PB 5 cm
