Question

Please help me solve these

(i). Calculate the volume exhaled by the patient as the function of time and give the total volume of air exhaled if R1=100Kohm, C= 2uf. The patient exhales rapidly at a constant rate change of 2 lit/sec for 3 min. where Ap=-200, K=100 lit/sec When the wheat stone bridge bias is Vbb=1Ov, R=10ohm. Find out the ouput voltage Vout (6 marks).

(ii). A spiromeler of radius 14cm, maximum height of 8cm if Vbb=20V. Find out the air volume and the output voltage Vout (4 marks)
