Sentence examples for groups of pipes from inspiring English sources

Now, to know the impact of changing C values on pressure heads at observation nodes, the C values of different groups of pipes were changed (herein reduced by 5), one by one, and the pressure head values on the observational nodes were noted as shown in Table 3.

In some types of this heat exchanger, a group of pipes are placed into larger pipes.

They further showed that monotonic behavior continues when the pipe roughness of the group of pipes is changed simultaneously.

Thus, if the observed pressure at the node is more than the modeled pressure and the impact of increasing the roughness value for a particular group of pipe is to increase the pressure head at the observation node, then the pipe roughness value for that group of pipes needs to be increased, or otherwise.

Hence, this calibration process assumed that the prepared data and predicted nodal demands were reasonably accurate and the model calibrated by adjusting only the pipe roughness coefficients for the group of pipes by the same amount to minimize the summation of the sum of square of difference between the measured and simulated values of the pressure heads (Eq. 4) at the observation points.

The model is calibrated by adjusting the NRW demand uniformly and the pipe roughness coefficients for the group of pipes by the same amount to minimize the summation of the sum of square of difference between the measured and simulated values of the pressure head at the observation points (Greco and Del Guidice 1999; Greco and Di Cristo 1999).

PRHRS consists of a steam generator (SG), a cooling tank with two groups of cooling pipes, an air-cooling heat exchanger (AHX), an air-cooling tower, corresponding pipes and valves.

Groups of five pipes are gathered in a collector equipped with a fan.

A common superheater is a group of parallel pipes with their surfaces exposed to the hot gases in the boiler furnace.

Three groups of wickless heat pipes having three different cross section geometries (namely, circular, elliptical and semi-circular cross sections) were designed and manufactured.

In each aquarium, one air stone provided gentle aeration and three groups of polyvinyl chloride (PVC) pipes (each pipe were 21 × 6.5 × 10.5 cm, radius × diameter × length), arranged as a pyramid, were allocated to minimize cannibalism by acting as shelters.
