How did British authorities manage to secure the commitment of large dominion and Indian armies that could plan, fight, shoot, communicate, and sustain themselves, in concert with the British Army and with each other, during the era of the two world wars? This is the primary line of inquiry for this study, which begs a couple of supporting questions. What did the British want from the dominion and Indian armies and how did they go about trying to get it? How successful were they in the end? Answering these questions requires a long-term perspective—one that begins with efforts to fix the armies of the British Empire in the aftermath of their desultory performance in South Africa (1899–1903) and follows through to the high point of imperial military cooperation during the Second World War. Based on multi-archival research conducted in six different countries on four continents, Douglas E. Delaney argues that the military compatibility of the British Empire armies was the product of a deliberate and enduring imperial army project, one that aimed at ‘Lego-piecing’ the armies of the empire, while, at the same time, accommodating the burgeoning autonomy of the dominions and even India. At its core, this book is really about how a military coalition worked.

The seventeenth century marked a high point in the Presbyterian experiment. A variety of models were tested internationally, and apologists for its polity offered a rigorous defense against Episcopalians, Congregationalists, and Erastians. The Westminster Assembly offered Presbyterians the first opportunity since the Reformation to model a fully Reformed church in England, and the gathering looked closely not only at the teachings of Scripture on ecclesial governance, but also at historical and contemporary models of connectional, nonhierarchical government to guide their formulations on church polity. The century also saw some of the worst persecution of Presbyterians, especially in France and Scotland, but also in England and central Europe. During their seasons of suffering, some Presbyterians found subtle ways to articulate their polity or identify essential elements of Presbyterianism. Others fought or fled hostile authorities, supplying a legacy of martyr narratives and missionary impulses for later Presbyterians.

Purpose The velocity head is usually neglected in the energy equation for a pipeline junction when one-dimensional (1D) hydraulic transient flow is solved by method of characteristics. The purpose of this paper is to investigate the effect of velocity head on filling transients in a branched pipeline by an energy equation considering velocity head. Design/methodology/approach An interface tracking method is used to locate the air–water interface during pipeline filling. The pressured pipe flow is solved by a method of characteristics. A discrete gas cavity model is included to permit the occurrence of column separation. A universal energy equation is built by considering the velocity head. The numerical method is provisionally verified in a series pipeline and the numerical results and experimental data accord well with each other. Findings The numerical results show that some differences in filling velocity and piezometric head occur in the branched pipeline. These differences arise because the velocity head in the energy equation can become an important contributor to the hydraulic response of the system. It is also confirmed that a local high point in the profile is apt to experience column separation during rapid filling. Significantly, the magnitude of overpressure and cavity volume induced by filling transients at the local high point is predicted to increase with the velocity in the pipes. Originality/value The velocity head in the energy equation for a pipeline junction could play an important role in the prediction of filling velocity, piezometric head and column separation phenomenon, which should be given more attention in 1D hydraulic transient analysis.
