The picture below depicts a system for delivering chocolate ganache in liquid form. Thenozzle on the end of the hose requires 140 kPa of pressure to operate effectively. Thehose is smooth plastic with an ID of 25 mm. The chocolate has a specific gravity of 1.1and a dynamic viscosity of 2.0 X 10-3 Pa*s.

An incompressible fluid flows through a pipe without significant viscosity. It has a density of 124 kg per cubic meter. In a section of pipe with a 2.8 cm radius the fluid moves at a speed of 13 m/s, and has a pressure of 103,763 pascals. It flows into a section of pipe with a 3.87cm radius that is 5 meters higher than the first section. What the pressure in the second section of pascals?
