Consider an air compressor operating steadily. How would you compare the volumetric flow rates of the air at the compressor inlet and outlet? Will the temperature of air rise as it is compressed by an adiabatic compressor?
Three screws are drawn at random from a lot of 100 screws, 10 of which are defective. Find the probability that the screws drawn will be nondefective in drawing (a) with replacement, (b) without replacement.
A given device has been determined that it attenuates 4.8dB in power from its input terminal to its output terminal. What is the output power in watts if a 150-W input has been launched into a system that has two of this type of devices
Consider a series RL circuit with a voltage source. Take the output as the voltage across the resistor with L = 2 henrys and R = 4 ohms. (a) Find the zero input response as a function of time. The initial current is 2 A.
