Question 1 A boiler system for the distillation column uses a control valve, flow controller and a pressure controller. Given the following data and assuming that they are related in series Determine the overall failure rate, the reliability and the MTBF for this system. Assume a 1-yr period. Component Failure Rate u (Faults/yr) Control Valve 0.35 Flow Controller 0.15 Pressure Controller 0.25 Given Equation R = e-ut P = 1 - R 1 MTBF Parallel: P = 11 P = (Px) * (P2) X....X (PH) i= 1 n = Series: Ro = R; = (R1) > (R) X.....X (Rn) i = 1
