Mass flow rate is the amount of mass flowing through a cross-section per unit time whereas the volume flow rate is the amount of volume flowing through a cross-section per unit time. 5-3C The amount of mass or energy entering a control volume does not have to be equal to the amount of mass or energy leaving during an unsteady-flow process. 5-4C Flow through a control volume is steady when it involves no changes with time at any specified position. 5-5C No‚ a flow with the same volume flow rate

higher measurement of flow rate compare to vegetable seeds. This result was reliable since the granular diameter of sugar was lower than vegetable seeds thus resulting a lower time consumed by coarse sugar to pass through hopper. However‚ as the orifice size was decreased‚ the flow rate was also decrease for both coarse sugar and vegetables seeds. The results of mass flow rate of experiment was quite tally with the mass of flow rate of equation. It shows decrement of flow rate as the orifice size decreases

purpose is to decrease or increase the flow and the pressure of the fluid in a desired direction. Impellers can be classified on the basis of flow regime: Radial flow impellers and axial flow impellers. Impellers can also be classified further into three types: paddles‚ turbines and propellers. Radial flow impellers typically find their usage where there is need to mix two or more immiscible fluids or there is need of mixing highly viscous fluids. Axial flow impellers on the other hand are used

two major purposes: (1) the pressure reduction from the condenser to evaporator pressure and (2) the regulation of refrigerant flow into the evaporator. These expansion devices can be generally classified into two types which are namely the fixed opening type (flow area is fixed) and the variable opening type (flow area changes correspondingly with a change in mass flow rates). There are about seven basic types of expansion devices for a refrigerant in a refrigeration system. These include capillary

Impact Of a Jet Introduction: Over the years‚ engineers have found many ways to utilize the force that can be imparted by a jet of fluid on a surface diverting the flow. For example‚ the pelt on wheel has been used to make flour. Further more‚ the impulse turbine is still used in the first and sometimes in the second stages of steam turbine. Firemen make use of the kinetic energy stored in a jet to deliver water above the level in the nozzle to extinguish fires in high-rise buildings

Experiment 1: Calibration of Volumetric Glassware Introduction: Volumetric glassware is used to accurately measure volumes. Despite all of the tools and instruments available for the use of measuring values of various data‚ it is impossible to measure the true value of anything. This experiment is intended to develop a person’s capacity to handle volumetric glassware. One must understand how to handle volumetric glassware to acquire the best possible data from the equipment used in lab. Although
