Exercise 2: According to an appliance manufacturer, the 4-in.-diameter vent on a clothes dryer is not to contain more than 20ft of pipe and four 90° elbows. Under these conditions determine the air volumetric flow rate if the gage pressure within thedryer is 0.20 inches of water. Assume both the specific weight and the kinematic viscosity of the heated air to be constant andequal toy=0.0709 bf/ft?, andv=µp=1.79x10 -4 ft2/s,respectively, and that the roughness of the vent pipe surface is equivalent to that of galvanized iron.C200.2 in.V-0(2)Figure K: Schematic for Exercise 2, Moran&Shapiro, 2002O KFVD) = 3.87O K fVD)= 3.67)O K/ (FVD) = 3.79O K/ (FVD) = 3.74

Air enters a diffuser operating at steady state at 540°R, 15 lbf/in.², with a velocity of 600 ft/s, and exits with a velocity of 60 ft/s. The ratio of the exit area to the inlet area is 8. Assuming the ideal gas model for the air and ignoring heat transfer, determine the temperature, in °R, and pressure, in lbf/in.², at the exit. Part A * Your answer is incorrect. Assuming the ideal gas model for the air and ignoring heat transfer, determine the temperature at the exit, in °R. T₂ = i -1244.63 °R
A well-mixed, insulated water storage tank is to be maintained at internal temperature 60°C. The environmental temperature around the tank varies from -25°C to 30°C.

! Required information Oil flow in a journal bearing can be treated as parallel flow between two large isothermal plates with one plate moving at a constant velocity of 5 m/s and the other stationary. Consider such a flow with a uniform spacing of 0.5 mm between the plates. The temperatures of the upper and lower plates are 40°C and 15°C, respectively. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Vm/s u(y) The properties of oil at the average temperature of (40+15)/2 = 27.5°C are k = 0.145 W/m-K and μ = 0.605 kg/m-s = 0.605 N-s/m² By simplifying and solving the continuity, momentum, and energy equations, determine the maximum temperature and where it occurs. The maximum temperature is 337.32 °C. The location of the maximum temperature is 0.369 mm above the bottom plate.
Employees on the second floor of a multi-story office building have been complaining about indoor air quality. Employees are convinced that there's "something in the air" because several employees report they only have symptoms at work, and the symptoms disappear as soon as they leave the office. A consultant proposing to be an indoor air quality expert provided a report with the following information about air samples collected on the second floor: 1200-1300 ppm carbon dioxide62-78% relative humidity.05 ppm formaldehyde (direct reading colorimetric tube)278 – 372 counts/m3 total airborne mold spores inside8,390 – 11,150 counts/m3 total airborne mold spores outside That's all the information you have. What additional information do you need to be able to evaluate the situation? Begin your discussion with your initial impressions and interpretation of the "consultant's" information. What conclusions, if any, can you make from the test results provided? Then, provide at least two…
