Question

Which one of the following is correct? The pressure in a pump suction line is higher than that in a return line. The flow speed in a return line is higher than that in a high pressure line. It the diameter of a high pressure line is larger than optimum, it causes excessive pressure drop. If the conduit is undersized, the flow speed in that conduit can be too low. None of them Which one of the following is correct? If the inner diameter of a conduit is too small for given flow rate, the flow velocity may be too low. If the inner diameter of a conduit is too large, it can cause too much pressure drop. The inner diameter of a 1-inch tube is larger than that of a 1-inch hose. The outer diameter of a 1-inch tube is larger than that of a 1-inch pipe. None of them
