A student is required to design an audio amplifier, which over audio frequencies, delivers 20 Watts to an 8-ohm speaker, when a 100-mV peak signal is applied to the input. Develop a test plan to verify that all requirements below have been met. Required:
a. Provide a description of the item to be tested and pertinent requirements.
b. Describe any electrical/environmental regulations or mandates that the system must be tested against.
c. Indicate any risks or issues that relate to product testing. For example, issues related to human safety or product damage that could occur when testing.
d. Describe the overall test approach to be used to test the product. This should be a top level description including the number of times the test will be run and under what conditions. Also, is this a test of single unit or multiple units? If multiple units, how many will be tested?

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
