The compressed air requirements of a textile factory are met by a large compressor that draws in 0.6 m3/s air at atmospheric conditions of 20°C and 1 bar (100 kPa) and consumes 300 kW electric power when operating. Air is compressed to a gage pressure of 8 bar (absolute pressure of 900 kPa), and compressed air is transported to the production area through a 15-cm-internal-diameter, 83-m-long, galvanized steel pipe with a surface roughness of 0.15 mm. The average temperature of compressed air in the pipe is 60°C. The compressed air line has 8 elbows with a loss coefficient of 0.6 each. If the compressor efficiency is 85 percent, determine the pressure drop and the power wasted in the transportation line.

A garden hose attached with a nozzle is used to fill a 40-literbucket. The inner diameter of the hose is 2.0 cm, and it reduces to1.0 cm at the nozzle exit. If it takes 59N s to fill the bucket withwater, determine (a) the volume and mass flow rate of waterthrough the hose, and (b) the mean velocity of water at the nozzleentry and exit
A pump increases the water presssure from 8kPa at the inlet to 700 kPa at the outlet. Water enters this pump at 41.51 degrees celsius through a 1.145-cm-diameter opening and exits through a 2.821-cm-diameter opening. Determine the velocity of the water at the outlet in m/s when the mass flow rate through the pump is 1.354kg/s. The specific volume of incoming water is 1.547x10-3m3/kg.
What do you understand by flow work? Is it different from displacement work?
Air flows steadily through an adiabatic compressor at a rate of 0.16 kg/s. The inlet conditions are 400 K and 100 kPa, and the exit conditions are 700 K and 1 MPa. If the power input is 49.92 kW, determine if this device violates either the first or second law of thermodynamics.
Include a free body diagram Air enters a nozzle steadily at 2.21 kg/m3 and 30 m/s and leaves at 0.762 kg/m3 and 180 m/s. If the inlet area of the nozzle is 80 cm2, determine (a) the mass flow rate through the nozzle, and (b) the exit area of the nozzle.
Air flows in a steady manner through a converging tube. At the inlet there are 690kPaa and 1.193m3/kg. If 125m3/min of air enters at the rate of 1.57 m/sec and the exit section has a diameter of 35cm, determine (a) the mass flow rate in kg/sec, (b) the diameter of the entrance section in mm and (c) the exit velocity in m/min.
Turbines, compressors, boilers, condensers, and heat exchangers operate for long periods of time under the same conditions, and they are classified as __________ flow devices.
