The pipeline has an open globe The 12 cm galvanized steel pipe shown is 800 m long and discharges water into the atmosphere. The pipeline has an open globe valve and four threaded elbows; h1 = 3 m and h2 = 15 m. What is the discharge, and what is the pressure at A, the midpoint of the lineAnsweredKristin asked 1 year ago • Mechanical Engineering731 views32 answers0 votesA reciprocating compressor of mass 20 Kg runs at a constant speed of 3000 rpm. After installation the forcing frequency is found to be too closer to the natural frequency of the system. Design a dynamic vibration absorber such that (a) the natural frequency of the main system is equal to that of the absorber and (b) the ratio of the operating frequency to the natural frequency is 0.75.Answeredali asked 11 months ago • Mechanical Engineering126 views2 answers0 votesA motor generator unit of mass 150 Kg runs at a constant speed of 1500 rpm.

The impeller of the blower rotates at 950 rpm and has a radius of 28 cm and a blade width of 3.1 cm at the outlet, and a radius of 13 cm and a blade width of 5.8 cm at the inlet. Assume that the tangential components of the air velocity at the outlet and inlet are equal to the impeller velocity at the respective locations and disregarding any losses; (a) Adopt a best practice approach, illustrate the problem in a diagrammatic form and identify the key assumptions that can be made. (5 marks) (b) Develop expressions to represent the torque and the shaft power. (4 marks) (c) Determine the volumetric flow rate of the air (take the gas constant of air to be 0.287 kPa m³/kg K) (5 marks) (d) Determine the normal components of velocity at the inlet and outlet of the impellerAnsweredMohamed Raseen asked 7 months ago • Mechanical Engineering127 views1 answers0 votes Question By Categories For your ease we have categorised questions into their respective subjects.
