A WTP Operator is trying to size a pump that takes water from a WTP holding tank and sends it to a house on a hill above the plant. The operator's goal is to have 60 psi of water pressure entering the house. The operator knows that the head loss (major+minor) from the holding reservoir to the pump is three times the velocity head in the 8 inch diameter pipe, and the head loss from the pump to the house is seen times the velocity head of the pipe. If the pressure head at the inlet of the pump is -8ft and the velocity head entering the house is the same as the velocity head in the pipe at the pump, determine what pressure head is needed from the pump to achieve the operator's goal of 60 psi of water pressure. (hint: notice the velocity head at the house is the same as the velocity head in the pipe at the pump
An old wooden telephone pole with a single cross member was blown off center during a recent storm. To temporarily stabilize the telephone pole, a repair crew has attached a cable from the end of the cross member to an eye-ring stake anchored in t..

Draw a plan of a typical strip mine showing all operational features and equipment and why is the working slope of an open pit usually much flatter than the final slope?
water at 150 degrees in a beaker is placed in an airtight chamber. Air is gradually pumped out of the container. What reduction below atmospheric pressure of 14.7 psi must be achieved before water boils
The L bracket shown below is pinned to the ground at point C and attached to a single cable at points A and D that wraps around a frictionless pulley at point B. Determine the forces acting on the bracket at point C and then tension in the cable.
It is required to dewater a construction site 80 m by 80 m. The bottom of the construction will be 1.5 m below the initial water surface elevation of 90 m.
A rod consisting of two cylindrical portions AB and BC is restrained at both ends. Portion AB is made of steel (E=29x10^6 psi, α=6.5x10^-6) and portion BC is made of aluminum (E=6.5x10^-6 psi, α=13.3x10^-6).
