What will be an ideal response?
What is its temperature at another section where its velocity is 50 
?
An ideal gas flows through a horizontal tube at steady state. No heat is added and no shaft work is done. The cross- sectional area of the tube changes with length, and this causes the velocity to change. Derive an equation relating the temperature to the velocity of the gas. If nitrogen at 150°C flows past one section of the tube at a velocity of 2.5 
Assume 
.
A ____ is a device that provides a degree of resistance in an electronic circuit, and under certain conditions either allows current to pass through it freely or blocks the flow completely.
A. capacitor B. semiconductor C. inductor D. coil E. none of the above
A 2,300/240-V, 60-Hz, 4.6-kVA transformer is designed to have an induced emf of 2.5 V/turn. Assuming an ideal transformer, find:
a. The numbers of high-side turns Nh and low-side turns Nl . b. The rated current of the high-voltage side Ih . c. The transformer ratio when the device is used as a step-up transformer. Assumptions: It is an ideal transformer.
