Nominal rating

Many initiators attack steels of the AISI 4300 series and the barrels of the intensifiers, which are usually of compound constmction to resist fatigue, have an inner liner of AISI 410 or austenitic stainless steel. The associated small bore pipework and fittings used to transfer the initiator to the sparger are usually made of cold worked austenitic stainless steel. The required pumping capacity varies considerably from one process to another, but an initiator flow rate 0.5 L / min is more than sufficient to supply a single injection point in a reactor nominally rated for 40 t/d of polyethylene.

If an upper limit is imposed on the amount to be paid by the user, the effect is similar. If the limit does not exceed the amount spent by the patient, given the price of the medicine and the co-payment rate, it is as if no limit had been imposed the effective co-payment rate is the nominal rate (c). In the opposite case, patients jump to consuming the quantity 0max, as if they were totally insured, without co-payment. In this case too, the contribution made by each party to foot the bill is affected. 

A boiler house contains five coal-fired boilers, each with a nominal rating of 300 boiler horsepower (BHP). If economically justified, each boiler can be operated at a rating of 350 percent of nominal. Due to the growth of manufacturing departments, it has become necessary to install additional boilers. Refer to the following data. Determine the percent of nominal rating at which the present boilers should be operated. Hint. Minimize total costs per year BHP output.

The granular treatment was applied on May 2nd, 1974 by spreading Treflan 5G commercial formulation from a conventional gravity fed spreader at a nominal rate of 0.7 kg/h of active ingredient. On May 8th, the emulsion-plot received 0.66 kg/h trifluralin as a spray of Treflan 4EC emulsifiable concentrate diluted with water according to commercial practice.

Formulate and solve the kinetics problem with the nominal rate constants and equilibrium constants. Compare the performance of the stiff and nonstiff methods. 

C-rate A method for expressing the rate of charge or discharge of a cell or battery. A cell discharging at a C-rate of T will deliver its nominal rated capacity in 1/t h e.g. if the rated capacity is 2 Ah, a discharge rate of C/l corresponds to a discharge current of 2 A, a rate of C/10 to 0.2 A, etc. 

The reaction can easily be mastered by the cooling system of the reactor, provided the stirrer works and the addition of reactants is at the nominal rate. 

Figure 22.7. Comparison of model (thin line) and experimental (thick line) temperatures for the cooling of tempered chocolate at a nominal rate of 2 C/min. The model uses apparent specific heat capacity data taken from DSC measurements at a cooling rate of 2 C/min (Tewkesbury, Stapley and Fryer 2000).

Graded-density submicron depth filters (Fig. 18.13) are suitable for broader PSD slurry global distribution loop filtration. These filters with large surface area and low face velocity are suitable for high flow POU and POD filtration applications, are typically disposable in nature, and may have nominal ratings of 0.2, 0.3, 0.5, and 1.0 pm.

This study shows the significant benefits of an MLP pump in handling shear-sensitive CMP slurries in single-pass applications and under normal turnovers ( 100) expected in a typical fab operation. Since, the MLC pump generated far fewer >lpm particles in shear-sensitive slurries, the filter lifetime for MLC pump-based slurry delivery systems should be longer than the other AOD or bellows pump-based systems, especially when relatively open (> 1 pm nominal rating) filters are used in the global loop and point-of-use (POU) locations. 

Two sets, i.e., four experiments, of core flow studies are compared. Sets No. 1 and No. 2 were tertiary miscible and immiscible CO2 floods without mobility control. The same core from each set, after plain CO2 injection, was restored to waterflood residual oil saturation and flooded with 0.05% AEGS 25-12 surfactant in brine. There was almost no difference between the oil saturation distributions in the cores between experiments, with the average Sorw values of 37 1 saturation percent in both sets of experiments. CO2 was injected continuously in all experiments at a nominal rate of 1 ft/day. No attempt was made to preform a foam, or to inject alternate slugs of surfactant solution and CO2. 

The overall pyrolysis behavior of the bituminous coal and lignite under 1 atm helium is summarized in Figures 2 and 3. These data were obtained by heating 53 to 88-fim diameter particles at a nominal rate of 1000°C/sec to the peak temperature indicated on the abscissa and then immediately permitting the sample to cool at a rate of about 200°C/sec. The ordinate of each data point represents the integral yield over the actual experimental time-temperature history. The data are plotted cumulatively up to the total weight loss of the sample, with the vertical separation between successive curves representing the contribution of the indicated products.

Nominal rate constants were adjusted to reconcile computed results with measured values. For example, the (OH + HC)-rate was cut to about one-third the estimated value, and the (NO + R02)-rate was increased eightfold. Reaction rates which have been reported individually in the literature were held at their nominal values, including the (O - - HC)-rate which we had to increase many-fold in The Original Scheme. Also, the retention of Reaction (5) was still necessary to describe the continued CsHe-decay after the near disappearance of NO. 

The start button is then pressed, the glycerine pipe is extended to the nitrator, glycerine and mixed acids begin to flow at the selected production rate between the nominal rate (100%) and reduced to 50%.
