impeller turning. An engineer must determine the range of flow rates required when using a centrifugal pump. The centrifugal pump chosen for an application must have a head versus flow rate relationship matches the demand of the piping system connected to. Head and flow rate data can be presented in graphical or table form. Discussion and Conclusion The result of conducting this experiment for characterizing the head and flow rate relation is summarized in Table 1‚ Figure 1 and Figure 2.

Saturated vapor at 60C enters the turbine‚ and the condenser operates at a pressure of 6 bar. The rate of energy input to the collectors from solar radiation is 0.4 kW per m2 of collector surface area. Determine the minimum possible solar

required by the pressure sensors‚ additional tappings are included in the ducts to allow appropriate calibration instruments to be connected. The flow of air through the compressor is regulated by a throttle control device installed at the exit of the discharge duct. Rotation of the collar opens and closes a variable aperture which allows the head/flow produced by the compressor to be varied.

Melt Flow Analysis Abstract: Polyethylene’s melt flow properties at 190°Cwere identified through the use of an extrusion plastometer. The data obtained was used to determine the average melt flow rate and melt flow index. Introduction: Polymers are an important class of materials. The range of properties of polymeric materials allows it to be essential in everyday life. The simplest polymer is polyethylene which consists of long chains of C2H4 monomers. Each monomer is joined by a covalent

Chapter 5: Flow Rate and Capacity Analysis 5.1 Objective Chapter 3 introduced the three basic building blocks of process flow namely the (average) flow time‚ (average) flow rate and (average) inventory. It is followed by a sequence of three chapters‚ 4‚ 5 and 6‚ which examine each one of these measures individually. Chapter 5 is concerned with flow rate analysis and issues of capacity. The major managerial concept discussed in the in the chapter is that of the bottleneck. We use the notion

Abstract This is an experiment about procedures of calibration of a Coriolis mass flow meter. To do the experiment‚ water is pumped from a reservoir and its flow rate is set by a tap‚ the height drop is examined by eye and the time is recorded for a period during the flow. This procedure is arranged for the calibration of the Coriolis meter by comparing the calculated mass flow and the read value. Although‚ it is a reasonable aspect for the calibration which is comparing digital and analog measurement

caused by impact of a jet into a flat plate or curved vane‚ the change in momentum principle is applied; Force = Rate of change in momentum F = ρ Q ΔV F = ρ Q (Vin – Vout) Where; F: the force exerted by the jet on the plate. ρ: the mass density of water (= 1000 kg/m3). Q: volumetric rate of flow (m3/s). ΔV: the change in velocity just after and before impact. The volumetric flow rate in the equation ’Q’ is calculated in the experiment by taking an amount of volume in a known period of time and
