3. [Adapted from Crowl 10-12) A horizontal vessel, 3m long and im in diameter, contains water. What relief size is required to protect the vessel from fire exposure? Assume the following: vapor relief only, MAWP of 14 barg, conventional capacity-certified spring-operated relief. Hint, your steam tables from previous classes will come in handy here. 6. (4 pts) A confined aquifer is pumped at a constant rate of 48,000 ft3/d from a 1 ft diameter well until equilibrium (steady-state) conditions are achieved. The drawdown measured in observation wells 150 ft and 300 ft from the pumping well are 41 ft and 8.8 ft, respectively. If the aquifer thickness is 100 ft: 0=48,000 ft thickness=looft a) compute the transmissivity in ft/d
