Design a common-emitter npn amplifier that has a voltage gain of 15. The supply voltage is VCC = +15V. The quiescent current should be set to IC = 0.5mA. The collector should have a quiescent voltage that is half the VCC

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

List and describe in sequence the operation process steps for boxf machine?

An ideal vapor-compression refrigeration cycle is employed to maintain a building temperature of 23°c when the outside temperature is 37°c. the cycle operates at steady state using ammonia as the working fluid. the mass flow rate of the refrigerant is 15 kg/min. the refrigerant enters the compressor at 1.5 bar and 10 °c. the condenser pressure is 20 bar and the temperature at the condenser exit is 45 °c. determine (a) the compressor power in kw. (b) the refrigeration capacity in tons. (c) the coefficient of performance. d) the maximum theoretical coefficient of performance.
