Design a first–order high-pass filter with a cutoff frequency fc = 1.5 kHz and a passband gain |Ao| = 20dB, using a capacitor C = 47nF. Include a compensation resistor and determine its value. (b) Sketch the frequency response for the circuit (i. e., magnitude vs. frequency and phase vs. frequency). On the magnitude response plot, indicate the cutoff frequency, bandpass gain, and bandstop rolloff slope. On the phase response plot, indicate the approximate value of the phase angle at f = 0.1fc, f = fc, and

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
