A compressor is designed to have inlet operating conditions $($pressure $1$ bar, Flowrate $300$ SCFM$)$ and outlet pressure $($pressure $50$ bar, Flowrate $300$ SCFM$).$ However, with increasing service life, now at t $200$ days the operational condition of the outlet becomes tpressure $35$ bar, Flowrate $100$ SCFM$).$

a$.$ Determine the reliability at $200$ days. Determine reliability at t $=200$ days

b$.$ Determine the constant failure rate using an order I approach, and determine the reliability prediction at t $=250$ days.
