According to syllabus of University of Pune, Fluid Machinery is third year second semester subject. As name suggests, we got to study tonnes of machines related to fluids, their performances and much more. As per university pattern complete subject is divided into six main units. Each unit is composed of similar topics. In exam each unit is asked for about 16 to 18 marks.
Introduction to Hydrodynamic Machines:
This is, as usual, fundamental topic which teaches us basic and creates foundation of subject so one may guess as relatively easy topic. And that’s true here. It lightens us with concepts like hydrodynamic head, fundamental equation, efficiency, hydraulic efficiency etc.
Impulse Turbine and Reaction Turbine:
Each of the above are complete unit itself. So relatively important topics and interesting though. Both have similar kind of calculations like velocity diagrams, analysis, speed ratio, flow ratio, velocity triangle, condition for maximum efficiency etc. Pelton wheel comes under impulse turbine while Francis turbine, Kaplan Turbine, Deriaz are reaction turbines.
Governing, Performance and Selection of Turbine:
Up till this unit, students are familiar with turbines. Here are discussed various governing methods for turbines, model analysis etc.
Hydrodynamic Pump:
This is another kind of Fluid Machinery. It covers up concepts related to centrifugal pumps like head, velocity triangle, cavitation, NPSH, priming of pumps, specific speed of pump, classification, performance etc.
Reciprocating and Special Pumps:
This chapter is like school of pumps. Here we learn reciprocating pumps, airlift pump, regenerative pump, hydraulic ram, deep well pump, vertical turbine pump and still more. Last unit also covers one more topic that includes fluid coupling and torque converter.
So, this is something about fluid machinery.
Thanks for Reading.
