Problem 44P

Water of density ρ= 998.2 kg/m3  flows through a fireman’s nozzle—a converging section of pipe that accelerates the flow. The inlet diameter is d1 = 0.100 m, and the outlet diameter is d2 = 0.050 m. The average velocity, momentum flux correction factor, and gage pressure are known at the inlet (1) and outlet (2), as in Fig. P6–47. (a) Write an expression for the horizontal force Fx of the fluid on the walls of the nozzle in terms of the given variables. (b) Verify your expression by plugging in the following values: β1 = 1.03, β2 = 1.02, V1, = 4 m/s, P1,gage = 123,000  kPa, and P2gage = 0 kPa. Answer:(b) Fx = 583 N to the right

Psychology 111 Day 1: ○ Experience and behavior begin with the nervous system ● Biology: ○ The nervous system translates things and transmits that information ● There are two main parts of the nervous system ○ Central Nervous System (CNS) ■ Brain and spinal cord ○ Peripheral Nervous System (PNS) ■ All the remaining nerve cells in your body ○ Neurons speak a different language through chemical and electrical signals. Both systems are made up of neurons. 1: Dendrites 1: Dendrites 3: Terminal Endings (Axon Terminals) 2: Axon ● Huge system ○ 1 quadrillion neurons (1,000,000,000,000,000) ■ (to count this high would take 30 million years if you counted one neuron every second)
