Risk management and analysis problems. Fragility. Uncertainties. Fault Tolerant Systems. Explosion.

1. A propane tank is located 100 m away from the nearest buildings. The fragility to explosion can be expressed by p = 0 for I < 0.7 MPa • s p = aI for 0.7 < I < 1.3 MPa • s p = 1 for I > 1.3 MPa • s Accounting for various release and ignition scenarios, including uncertainties, the estimated probability distribution of impulses resulting from such explosions is given by the following set of values: I (MPa • s) 0.1 0.3 0.5 0.7 0.9 1.2 p 0.06 0.1 0.4 0.3 0.1 0.04 Supposing that you can improve the building so that you can affect the threshold of damage, increasing it above 0.7 MPa • s, and supposing the high end at 1.3 MPa • s remains the same, and so is the linear in-betw... click for more

Pump Problem

Ethylbenzene at 40 degrees C is delivered by a pump from a storage tank to a reactor elevated 3.5 m above the pump. The pressure at the inlet to the reactor is 1.5 barg. There is a control valve in the line, with a pressure drop of 0.75 bar across it. the flowrate of ethylbenzene is 8 L/s. What is the maximum flowrate possible with the valve fully open? If the tank is open to the atmosphere, what is the minimum required elevation of liquid in the tank? The tank is at atmospheric pressure. Please explain the procedure used to solve the problem in detail.
