Water at 80°C, 1 atm flows at an average velocity of 7 m/s in a horizontal pipe which has an internal diameter and a length of 0.2 m and 5 m, respectively. It is proposed to add eight symmetrically spaced 5 cm wide smooth, thin plates along the length of the pipe as shown. (Take pwater = 800 kg/m³, µwater = 357 × 106 Pa.sec at 80°C g = 9.81 m/s² and Reer= 500 000). a) Calculate the pressure drop in the pipe, Pa, without the plates.
