Forthe conditions shown in figs. 19.719- 19.10 0, complete the design of the duct system by specifying the sizes for all duct sections necessary to achieve a system that is balanced when it carries the flow rates shown. Compute the pressure at the fan outlet, assuming that the final outlets from the duct system are to atmospheric pressure. When an inlet duct section is shown, also complete its design and compute the pressure at the fan inlet. Note that there is no single best solution to these problems, and several design decisions must be made. It may be desirable to change certain features of the suggested system design to improve its operation or to make it simpler to achieve a balanced system.

- A pump is used to lift water at ambient temperature from one tank to another at a rate of 08/50 m3/min. If the pipe diameter is 4 in, calculate the power required to run the pump (efficiency 70%). The pipe material is commercial steel and contains 3 standard radius elbows. Assume h=1 cP. Calculate the Reynolds number and the friction head loss using the Moody chart attached, Using Colebrook equation. Calculate the other losses and the total loss, (Calculate the required power. Flow rate is not necessary for answering the question.arrow_forwardA well is going to be installed with a sucker rod pumping unit a. For the well to be installed with a sucker rod pump calculate the effective plunger stroke length for a well with a rod pump set at 3600 ft.
