Some penguins decide to build a 3m high shower on the iceberg. They buy a pump and install a pipe, as shown in the figure. The gauge at the inlet shows a pressure of pi = 90 kPa when pumping sea water and the inlet water speed is 0.5 m/s. The diameter at the inlet d is three times larger than the diameter at the shower output d. What is the reading of the pressure gauge at point 2? 0.5 m/s 90 kPa d d h=3m Co
