Figure Q1 above shows a diagram of blood flow from the left ventricle into the aorta (Q) as a function of time (t) during systole. The aortic valve opens at t=0s and closes at t=0.2s. During the first half of systole (0s < t < 0.1s), the flow Q is constant with a value of Qo. During the second half of systole (0.1s < t < 0.2s), the flow decreases linearly. Starting with the general solution for the aortic pressure (given in Part (b)) and assuming a stroke volume of 70cm^3, determine expressions for P(t) for the following time intervals: (i) 0s < t < 0.1s [5] (ii) 0.1s < t < 0.2s [5] (iii) 0.2s < t < 0.8s (diastole) [5]
