9:06 AM Tue May 5 6% Ims.manhattan.edu 3. The pressure rise, p, of a liquid flowing steadily through a centrifugal pump depends on pump diameter, D, angular speed of the rotor, ω, volume flow rate, Q, and density, ρ. a) Develop dimensionless variables for this process. (10 points) b) The following table gives data for the prototype and for a geometrically similar model pump. For conditions corresponding to dynamic similarity between the model and prototype pumps, calculate the missing values in the table.

A DC to DC converter needs to produce -50V from a 40V source. The load power needs to be at most 75W. The switching frequency is set to 100kHz. The output ripple must be no more than 1 percent. Also given that the current ripple cannot be more than 40% of the average inductor current. Find the inductor and capacitor value and their average and peak ratings.

#3.15 Speed graph and acceleration quantities A particle is moving with the speed $v$ shown below as a function of time. At $t = 12$ s the angle between the velocity and acceleration vectors of the particle is $\theta = 0.5$ rad. At the same time $t = 12$ s, what is the acceleration magnitude of the particle? $a = $ ____ $m/s^2$

True/False 1) Reflexes are rapid, automatic responses to stimuli. 2) Efferent nerve fibers may be described as motor nerve fibers. 3) Myelination of the nerve fibers in the central nervous system is the job of the oligodendrocyte. 4) During depolarization, the inside of the neuron's membrane becomes less negative. 5) Neurons in the CNS are organized into functional groups. 6) Strong stimuli cause the amplitude of action potentials generated to increase. 7) A postsynaptic potential is a graded potential that is the result of a neurotransmitter released into the synapse between two neurons. 8) Large-diameter nerve fibers conduct impulses much faster than small-diameter fibers. 9) Unipolar neurons have axons structurally divided into peripheral and central processes. 10) If bacteria invaded the CNS tissue, microglia would migrate to the area to engulf and destroy them. 11) The functions of the nervous system are sensory input, integration, and motor output. 12) The autonomic nervous system is under voluntary control; whereas, the somatic nervous system is involuntary. 13) Axon diameter and degree of myelination determine nerve impulse conduction velocity. 14) The action potential is caused by permeability changes in the plasma membrane. 15) Some neurotransmitters can be either excitatory or inhibitory depending upon the receptor.
