If the cross-sectional area of the passage were reduced downstream, determine the maximum percentage reduction of area allowable without reducing the flow rate (assume isentropic flow). Determine the speed and pressure at the minimum area

A steady stream of n-butanol is needed to be fed into the reactor at 40 ̊C. However, the inlet of the reactor is located 7.5 m above the reservoir tank. As such, a highly effective centrifugal pump (70% efficiency) is used for such a purpose. It was understood that the needed volumetric flow rate into the reactor is fixed at 20 m3/h. It was also noted that the n-butanol reservoir is closed but not pressurized, while the gauge pressure at the endof the discharge line is measured at 275 kPa. Given that the density of n-butanol is 810kg/m3. If the discharge pipeline was 5 cm in diameter, calculate: (i) The velocity of n-butanol at the discharge line. (ii) The total power input from the centrifugal pump. (iii) The power delivered to the n-butanol fluid.
