It can also be transformed into the pressure that the fluid would obtain where it to be held without any energy loss. Fluid Mechanics : Classification of Turbines Types of Fluid Flow: Steady, Laminar, Turbulent Flow and ... Answer: Definition of pump: The pump is a device that is used to pump fluid. Ideal fluid is not found in actual practice but it is an imaginary fluid because all the fluid that exists in the environment has some viscosity. Types of pumps. The manner in which fluid flows through the pump is determined by the design of the pump casing and the impeller. 924 Downloads. 2. Chapter. Different Types of Pumps Used in the World - Mechanical ... Part of the Studies in History and Philosophy of Science book series (AUST, volume 22) Pumps for raising water (hydraulic pumps) have been known since antiquity. Positive displacement pumps. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between pump and the fluid surface. Discharge = 6 lps, suction head = 4m, Delivery head = 20m, Find the energy required to drive the pump. Under this system, all pump types generally fall into two main categories - Dynamic (Centrifugal) Pumps - Energy is continuously added to increase the fluid velocities within the machine. = 1.409 kW. Motive fluid is provided through the inlet (yellow arrow in fig.4) of the ejector and the low pressure flare gas from the process vessel or reactor (yellow arrow fig. 4.

Fluid Mechanics and Machinery by D. Rama Durgaiah, New Age International. Classification of Centrifugal Pump Centrifugal pumps are classified in several ways. This type of fluid is also called as streamline flow or viscous flow. Types of Pumps Centrifugal pumps are subdivided into several categories; Axial flow, Mixed flow and Radial flow. The whole assembly is submerged in the fluid to be pumped. There are numerous types of pumps used in the industry. FLUID MECHANICS Chapter 12 Pumps and Turbines . Motive fluid can be anything that further can be compressed by ejector. Pumps are operated by the mechanism that is rotary, reciprocating and it consumes energy while performing mechanical work which is moving fluid from one place to another. In fluid dynamics, the head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. INTRODUCTION: Every day a student or a professional is looking for a short and timely handbook with practical information and comprehensive application for many technical subjects, including this essay of Centrifugal Pumps & Fluid Flow Calculations. Radial Flow Pumps: In these types of pumps the flow of fluid takes place in radial direction i.e. Part of the Studies in History and Philosophy of Science book series (AUST, volume 22) Pumps for raising water (hydraulic pumps) have been known since antiquity. Turbomachinery, in mechanical engineering, describes machines that transfer energy between a rotor and a fluid, including both turbines and compressors.While a turbine transfers energy from a fluid to a rotor, a compressor transfers energy from a rotor to a fluid. fluid mechanics .

In this chapter we will talk about the differences between the two pump types. The pressure or velocity of the fluid increases, which helps the fluid overcome physical barriers such as pipe friction and height changes. parallel to the axis of rotation) 2. kg m kgm-3 == V m3 water= 1000 kgm-3 air =1.23 kgm-3 f 1.2 SPECIFIC WEIGHT, Definition Specific weight of a fluid, , is defined as the weight of the fluid per . Fluid mechanics is a branch of continuum mechanics, a subject that models matter without using the information of what atoms they are made of. The flow supplied by a pump can be intermittent or continuous. The work is very simple, described well, and carefully tested. The relative spatial position of the prime mover (e.g., turbine) is fixed. 1). The Hydraulic Accumulator 2. The mechani-cal energy is provided by the pumps. A submersible pump is a pump which has a hermetically sealed motor close-coupled to the pump body. The Hydraulic Ram 5. Density of material may be referred to in many ways. Definition of pump, types of pumps , stages, working principle, application 12. Ideal Fluid: A fluid that can not be compressed and have no viscosity falls in the category of an ideal fluid. These pumps also tend to have a lower price, since mass production has brought down their manufacturing cost. Pumps operate by some mechanism (typically reciprocating or rotary ), and consume energy to perform mechanical work moving the fluid. pumps, fans, blowers and compressors). Usually used in water pipework systems and installed immediately after the pump. . in a pipe flow. Ideal plastic fluid. A systematical review of the applications of fluid mechanics in blood pumps. Energy required = r g Q ( Hs + Hd ) Watts = (1000 x9.81 x 6x10-3 x (4 + 20) / 1000. Centrifugal Pumps The centrifugal pump produces a head and a flow by increasing the velocity of the Work transferred to or from a fluid flowing through a pump or a turbine occurs by interaction between moving rotor blades and the fluid. The Hydraulic Lift 6. [Units are N/m 2 or Pa] ρ is the density of the fluid. Kumar Kataria & Sons. The Hydraulic Crane 7. Typical Pumping Installation The check valve is normally installed at the discharge side near the pump The gate valve is installed after the check valve. To move fluid from one place to another a positive displacement pump traps fluid and then forces it to the discharge pipe. Note: At 44:52, the equation should be Q = V*A, not Q = V/A.0:00:15 - Introduction to centrifugal pumps, measuring pump head0:04:09 - Pump performance curves.
