For the circuit below, assume the components have the following values: Vs = 8 vpp, Cf = 200 nF, Rf = 10000 Ω, Ri = 500 Ω and ω = 1000 rads/sec. Answer the following questions for ω = 1000 rads/sec. Format all answers to two decimal points. 1) What is the feedback impedance in phasor notation? Zf = at an angle of o Ω. 2) What is the impedance of the input in phasor notation? Zi = at an angle of o Ω 3) What is the magnitude of the gain of this circuit in v/v? G = v/v. 4) What is the magnitude of the output voltage, vout? vout = vpp. 5) What is the cutoff frequency? What kind of filter is this? Are we operating in the passband? fc = Hz and this is a filter, so

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

On a average work day more than work place firs are reorted
