A prototype air compressor with a compression ratio of 7 is designed to take \(8.9 \mathrm{~kg} / \mathrm{s}\) air at 1 atmosphere and \(20^{\circ} \mathrm{C}\). The design point speed, power requirement, and efficiency are \(600 \mathrm{rpm}\), 5.6 MW, and 80 percent, respectively. A 1:5-scale model of the prototype is built to help determine operability for the prototype. If the model takes in air at identical conditions to the prototype design point, what will the mass flow and power requirement be for operation at 80 percent efficiency?
