Discharge capacity Subject

However, all pump discharges are subject to friction and other losses, and it is therefore necessary to refer to various pump curves and design data in order to establish the correct pump design and to provide a precise match in terms of pump capacity, FW temperature, head demands, and mode of pump operation. 

Economically attractive applications for polymers include their use in sewers subject to occasional overload. If polymer dosing can be shown to provide the required extra discharge capacity in a particular case, then costly sewer rebuilding can be delayed or avoided. 

The discharge capacity of the trap depends on the flow area of the valve orifice, the pressure drop across it, and the inlet temperature of the condensate. There is a considerable problem in measuring the pressure drop because hot condensate flashes as it passes through the valve orifice. Trap capacity is not truly defined by orifice size and pressure differential. Pressures upstream and downstream of the trap are also subject to variation, depending on calandria performance, flowrates, temperatures, and system back pressure. The orifice may never be fully open to flow because of the valve design. Nor can flow coefficients be measured with the same precision as for control valves, since the valve stem in the trap is often not definitely located with reference to the orifice. 

The mechanism hy which these materials achieve such high discharge capacity is not yet completely clear, and many aspects of these materials are the subject of active research. There are notable reports focusing on their first-charge electrochemical behavior [16], mechanisms of deterioration [17], mechanisms of high durability [18], mechanisms of high capacity [19], mechanisms of ion transport [20], and the relationships between performance and the crystal structure [21]. 

Active materials for positive electrodes with excess lithium are now the subject of our attention because they are expected to have a large discharge capacity. 

In addition to large oil spills, petroleum hydrocarbons are released into the aquatic environments from natural seeps as well as non-point-source urban runoffs. Acute impacts from massive one-time spills are obvious and substantial. The impacts from small spills and chronic releases are the subject of much speculation and continued research. Clearly, these inputs of petroleum hydrocarbons have the potential for significant environmental impacts, but the effects of chronic low-level discharges can be minimized by the net assimilative capacities of many ecosystems, resulting in little detectable environmental harm. 

In order to determine which expls are capable of ignition by an electrostatic discharge of an energy amounted to 100000 ergs, or less it. is necessary to subject each prospective expl to the following energy requirement test . For this a layer of the expl is spread in thickness of 0.010 inch on a steel plate and is separated by a a short gap from a steel needle. This needle is so arranged that it can be thrown into a closed circuit with a condenser of known capacity, on... 

The construction of a cell involves a number of variables such as the relative amount and nature of the cathodic mix, type of separator used, etc. Fig. 3.12 illustrates the difference in service life between a standard GP cell and a HD cell which has been designed for high power applications when both are subjected to a heavy discharge (30 minutes once a day through a 2 Q load). For a similar construction and composition, and a fixed duty schedule, higher capacities are obviously obtained by using cells of larger size. 

Changes in space-charge capacity can be used to observe the effect of charging and discharging of electronic states in a semiconductor subject to sub-bandgap illumination. Show that the change in observed capacity caused by illumination can be referenced to the unilluminated case by...
