A planning study is being proposed for the pipe network of Example 4. 10. In particular, the water company wants to determine the impact of increasing the outflow at junction F from 0.25 m3/sec to 0.30 m3/sec. Although there is an adequate supply of water to meet this demand, there is a concern that the resulting pressure heads may become too low. Using the Newton method and appropriate computer software, determine if the pipe network can accommodate this increase satisfactorily if a minimum of 10.5 m of pressure head is required at every node.
