What is the expected pressure drop across a component if its flow coefficient is 12 gpmpsi- when the flow through it is 14 gpm? 12) What are the differences between NPTF fittings and SAE-ORB fittings? 13) Why should you avoid using NPTF elbow fittings? 14) When you set the pressure relief valve to a particular pressure by dead-heading the cylinder, is that the full-flow or cracking pressure? (Explain the difference
