- Consider an air solar collector that is 1 m wide and 5 m longand has a constant spacing of 3 cm between the glass cover andthe collector plate. Air enters the collector at 30°C at a rate of0.15 m3/s through the 1-m-wide edge and flows along the 5-mlong passage way. If the average temperatures of the glasscover and the collector plate are 20°C and 60°C, respectively,determine (a) the net rate of heat transfer to the air in thecollector and (b) the temperature rise of air as it flows throughthe collector.The velocity profile in a fully developed laminar flow of water at 40°F in a 250-ft-long horizontal circular pipe, in ft/s, is given by u(r) = 0.8(1 - 625r2), where r is the radial distance from the centerline of the pipe in ft. Determine (a) the volume flow rate of water through the pipe, (b) the pressure drop across the pipe, and (c) the useful pumping power required to overcome this pressure drop.A 6-m-tall chimney is to bedesigned to discharge hot gases from a fireplace at 1808C at aconstant rate of 0.15 m3/s when the atmospheric air temperatureis 208C. Assuming no heat transfer from the chimney and takingthe chimney entrance loss coefficient to be 1.5 and the frictioncoefficient of the chimney to be 0.020, determine the chimneydiameter that would discharge the hot gases at the desired rate.Note that P3 = P4 = Patm and P2 = P1 = Patm + ratm air gh, andassume the hot gases in the entire chimney are at 180°C.
- 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, plastic (smooth) pipes 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. In order to reduce the head losses in the piping and thus the power wasted, someone suggests doubling the diameter of the 83-m-long compressed air pipes. Calculating the reduction in wasted power, and determine if this is a worthwhile idea. Considering the cost of replacement, does this proposal make sense to you?Consider laminar flow of water in a 0.8-cm-diameter pipe at a rate of 1.15 L/min. The velocity of water halfway between the surface and the center of the pipe is (a) 0.381 m/s (b) 0.762 m/s (c) 1.15 m/s (d) 0.874 m/s (e) 0.572 m/sThe velocity profile in fully developed laminar flow in a circular pipe of inner radius R = 2 cm, in m/s, is given by u(r) = 4(1 − r2/R2). Determine the average and maximum velocities in the pipe and the volume flow rate.
- Air enters a 12-cm-diameter adiabatic duct with inlet conditions of V1 = 150 m/s, T1 = 500 K, and P1 = 200 kPa. For an average friction factor of 0.014, determine the duct length from the inlet where the inlet velocity doubles. Also determine the pressure drop along that section of the duct.Air enters a 7-m-long section of a rectangular duct of cross section 15 cm X 20 cm at 50°C at an average velocity of 7 m/s. If the walls of the duct are maintained at 10°C, determine: (a) the outlet temperature of the air, (b) the rate of heat transfer from the air, and (c) the fan power needed to overcome the pressure losses in this section of the duct.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.
- The velocity profile in fully developed laminar flow in a circular pipe of inner radius R = 4 cm, in m/s, is given by u(r) = 4(1 - r2/R2). Determine the average and maximum velocities in the pipe and the volume flow rate.The 64-W fan in an aircraft environmental system is to circulate air through the ducting. An analysis of the flow shows that the fan needs to raise the pressure of air by 47 Pa to maintain flow. The fan is located in a horizontal duct with a circular cross-section whose diameter = 30 cm at both the inlet and the outlet. Determine the highest possible average flow velocity in the duct. Give your answer in m/s. Assume the fan operates steadily and that the changes in kinetic and potential energies across the fan are negligible. Note: I start this one by finding the volumetric flow rate from the work input and the pressure rise. Then I divide that by the cross-sectional area of the duct to get velocity.A 3-m-diameter tank is initially filled with water 2 m above the center of a sharp-edged 10-cm-diameter orifice. The tank water surface is open to the atmosphere, and the orifice drains to the atmosphere through a 100-m-long pipe. The friction coefficient of the pipe is taken to be 0.015 and the effect of the kinetic energy correction factor can be neglected. Determine (a) the initial velocity from the tank and (b) the time required to empty the tank.
