Consider water flowing through a 10 m section of 4 inch ID smooth pipe followed by an abrupt contraction to a 1 m section of 0.25 inch IDsmooth pipe. If the water is flowing at 2 gal/min, calculate the total pressure drop over the two sections (remember to include the effect of the contraction).

MCQs on how fluids (gases and liquids and a few other materials) respond to forces, exert forces, and move from one place to another (their mechanics).
