Component options-valve design and when they should be used, point’s difference between plungers and piston rods and their selection criteria. Volumetric and mechanical efficiency, net head available and required plus piping required for suction and discharge. Basic principles of positive displacement reciprocating pumps. Reciprocating pump has wide applications in many industries, cautiously selecting equipment with the right configuration of options is essential in providing and operating the machine. The pump and system interaction is an important part of reliable operation.
A range of air flow rates from 0.15 to 3.5-g/L were used. In the second part, the effect of the air flow rate at constant heater temperature and changing power was studied. The same range of air flow rates were used and tested at three heater temperatures of 100, 125, and 150°C. The minimum fluidization velocity,
The same can be said for the soil that surrounds the water bowls. Although one may expect to find increased activity in the drinking area, one has to consider the impact of excess water on that surrounding soil. This will result in decreased penetration resistance, as we see in figure 1. Soils that are compacted at high moisture contents and high levels of organic matter will have considerably greater strengths than those with lower organic content.

Rainwater Harvesting System performance is strongly influenced by rainfall, water demand, and the storage tank capacity. The main objective of this study is to find the correlation between rainfall, water demand, and the storage tank capacity. Correlation is expressed by a non-dimensional parameter which is represented by the curves and equations based on tank capacity
The heater tempetureand the base temperature is maintained as 333K (60º C). This experiment is done for all the three type of fin arrays and the corresponding tempetature values are noted. The average value is taken for the three fin structures and the heat transfer coefficient is calculated. After that the result is compared with the CFD result. 4.2 Meshed Model Relevance centre: Fine Min.
CAVITATION IN MARINE CENTRIFUGAL PUMPS AND PIPES In a centrifugal pump during its operation the fluid that enters is accelerated by the impeller. At impeller the pressure lowers as the velocity increases (Bernoulli equation). The flow area at the eye of the impeller is usually smaller than either the flow area of the pump suction piping or the flow area through the impeller vanes. When the flowing liquid passes from the eye of the impeller the area that is smaller results in the increase of the velocity followed by the decrease of the pressure. If pressure is lower and/or the temperature is higher than the saturation pressure/temperature some fluid changes to vapour forming tiny bubbles.

So, an average of the lowest and the highest value was taken into
The dc voltage developed across each load resistance has been found to be related with fluid flow rate. Sum of the voltage signals developed for two horizontal IC's has been subtracted from that of the voltage signals for two vertical IC's. As a result the effect of temperature of the fluid is nullified and the resultant after this subtraction may be assumed to be a function of fluid flow rate only. The dc voltage developed in the differential op amp is of the order of mV signal. This signal is converted into 1-5 volt signal using instrumentation amplifier and signal conditioning circuit.
Figure (4 a,b) shows the dynamic analysis on mechtrode and deformation values Figure-4(a) Deformation of Mechtrode Figure-4(b) Deformation of Mechtrode TEMPERATURE FIELD IN MECHTRODE Figure 5 illustrate the temperature field at the center Section of the consumable-rod at different rotational speed. Prior to the completion of friction preheating, in other words, at a time shorter than preheating time (e.g., 10, 20, and 30 s), the main heat source is generated through friction, and the temperature profile along the radial direction represents. Consequently, when the temperature at the friction interface becomes sufficiently high, the material completely transforms into plastic, the stress field has likely become uniformed, and friction heat increases rapidly at the outer areas, such that the temperature profile along the radial direction represents. In this work we give different rotational force to the mechtrode (900, 1000, 1100, 1200, 1300, 1400, and 1500) rpm. Table 3 shows the simulation values for different rotational speeds.
The drainage density suggests permeability of subsoil. The bifurcation ratio indicates normal basin category. The analysis of the relative relief of the area comes under the category of 30-60 m and at some places relative relief is very high and it suggests rugged topography. The bifurcation ratio indicates normal basin category. Low form factor value 0.141 indicates basin elongation and structural and topographical control on the basin.
