Cardiac pacemakers are used by people tomaintain regular heart rhythm when they havea damaged heart. the circuit of a pacemakercan be represented as. the resistance of thewires, r, can be neglected since r < 1 mω.the heart's load resistance, r l , is 1 kω. thefirst switch is activated at t = t 0 , and the secondswitch is activated at t 1 = t 0 + 10 ms. this cycle is repeated every second. find v(t) fort 0 ≤ t ≤ 1. note that it is easiest to consider t 0 = 0 for this calculation. the cycle repeatsby switch 1 returning to position a and switch 2 returning to its open position. 0.6e − 2(t-0.1) v

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
