NPSHa Calculation for Pressurized Systems by Nor Azlan Awang is a document available to read on EtoBox.
This article discusses the calculation of net positive suction head available (NPSHa) for a closed and pressurized system, emphasizing the common mistake of confusing suction pressure with NPSHa. It provides a detailed example involving a deaerator tank operating at 120 psig and 350°F, illustrating the calculation process and the importance of considering absolute pressure and vapor pressure. The conclusion warns against neglecting NPSHa calculations, as relying solely on suction pressure can lead to costly
