Product mass flow rate

Write expressions for the quantities requested in the problem statement. In terms of the quantities labeled on the flowchart, the quantities to be determined are m2 (the overhead product mass flow rate), m3 = mss + mxs (the bottom product mass flow rate), xq = mB3/ 3 (the benzene mass fraction in the bottom product), and xt = 1 -. rs (the toluene mass fraction). Once we determine m2. B3, and mx3, the problem is essentially solved. [Pg.103]

Furthermore, in applications where products can be easily separated from the effluent stream, it can be convenient to operate atsmall dimensionless lengths at the expense of lower conversions. Product mass flow rate will increase, more than compensating for this reduction in conversion. [Pg.445]

A large-scale pneumatic conveying test rig was employed to transport the above four test materials. Two Afferent pipelines were connected to the test rig. The characteristics of the pipelines are listed in Table 2. The product mass flow rate, mg was determined from load cell readings and the air mass flow rate, mf was determined by an air flow sensor, Annubar. The static air pressmes were measured by the pressure transducers. [Pg.375]

On completion of testing, the data are analyzed and the pneumatic conveying characteristics plotted showing total pipeline pressure drop vs. supplied air mass flow rate with constant product mass flow rates, as shown in Fig. 2. Although this paper focuses on the dense-phase region, both dilute-phase and dense-phase tests have been performed for completeness. Based on observations made during each test, the approximate boundaries for both dilute- and dense-phase are displayed, see Fig. 2. [Pg.381]

Combined with the theoretical correlations [4], the pressure drop and the location of boundaries in the test pipeline were predicted. Fig. 12 shows the predicted pneumatic conveying characteristics of white polythene pellets in the test pipeline. The total pipeline pressure drop appears as solid black lines for different product mass flow rates and the boundaries appear as dashed lines. [Pg.385]

The location of upper boundary in Fig. 2 is different from that in Fig. 12, in particular at low product mass flow rates. The main reason is that when the product mass flow rate is low (i.e. less material is fed into the pipeline), the material in the pipeline is not enough for the slugs to be formed. [Pg.385]

Reactor heat carrier. Also as pointed out in Sec. 2.6, if adiabatic operation is not possible and it is not possible to control temperature by direct heat transfer, then an inert material can be introduced to the reactor to increase its heat capacity flow rate (i.e., product of mass flow rate and specific heat capacity) and to reduce...

For theJth. component, my = m iDy is the component mass flow rate in stream i is the mass fraction of component j in stream i and q is the net reaction rate (mass generation minus consumption) per unit volume V that contains mass M. If it is inconvenient to measure mass flow rates, the product of density and volumetric flow rate is used instead. [Pg.592]

Refrigerating capacity is the product of mass flow rate of refrigerant m and refrigerating effect R which is (for isobaric evaporation) R = hevaporator outlet evaporator mJef Powei P required foi the coiTipressiou, necessary for the motor selection, is the product of mass flow rate m and work of compression W. The latter is, for the isentropic compression, W = hjisehatge suction- Both of thoso chai acteristics could be calculated for the ideal (without losses) and for the ac tual compressor. ideaUy, the mass flow rate is equal to the product of the compressor displacement per unit time and the gas density p m = p. [Pg.1110]

Continuity relation The mass flow rate in unit time is the product of the density multiplied by the volume flow in unit time. [Pg.1424]

A similar argument can be used for a fuelled semi-closed cycle, assuming that it can be regarded as the addition of an open CBT plant and a closed CHT cycle with identical working gas mass flow rates (and small fuel air ratios). Suppose the latter receives its heat supply from the combustion chamber of the former in which the open cycle combustion takes place. If the specific heats of air and products are little different, then the work output is doubled when the two plants are added together, but the fuel supply is also approximately doubled. The efficiency of the combined semi-closed plant is, therefore, approximately the same as that of the original open cycle plant. [Pg.140]

In addition to the energy requirements of solid propellants, Eq. (3) shows that consideration must be given to the mass-flow rate of the combustion products through the nozzle. Because all solids burn on the exposed surface, the mass flow of propellant combustion products is given by the equation... [Pg.5]

Total mass flow rates are given by the product of volumetric flow multiplied by density. Component mass flows are given by the product of volumetric flow rates multiplied by concentration. [Pg.24]

The mass balance relationships for the feed plate, the plates in the stripping section, of the column and for the reboiler must, however, be modified, owing to the continuous feed to the column and the continuous withdrawal of bottom product from the reboiler. The feed is defined by its mass flow rate, F, its composition xp and the thermal quality or q-factor, q. The column bottom product is defined by its mass flow rate, W, and composition, xw and is controlled to maintain constant liquid level in the reboiler. [Pg.209]
