1.1 A 6 inches pipe carrying 3.93 cfs connects to a 6 inches pipe. Find the velocity head in the 6 inches pipe. 1.2 Sulfur dioxide flows through a 12 inches discharge duct that reduces to 6 in diameter at discharge into a stack. The pressures in the duct and discharge stream are. respectively, 30.0 psi absolute and atmospheric (14.7 psi). The velocity in the duct is 50.0 ft/sec, and the temperature is 80 F. Calculate the velocity in the discharge stream if the temperature of the gas is 23 F. 1.3 Water flows through a horizontal 100-mm pipe under a pressure of 414 kPa.

Calculate the velocity in the discharge stream if the temperature of the gas is 23 F. 1.3 Water flows through a horizontal 100-mm pipe under a pressure of 414 kPa. Assuming no losses, what is the flow if the pressure at a 75-mm diameter reduction is 138 kPa?
