An engineer is designing a subsonic wind tunnel. The testsection is to have a cross-sectional area of 4m2 and anairspeed of 60m/s. The air density is 1.2kg/m3. the areaof the tunnel exit is 10m2. The head loss through thetunnel is given by hL =(0.025)*(VT2/2g), whereVT is the airspeed in the test section.Calculate the power needed to operate the wind tunnel.Hint: assume negligible energy loss for the flowapproaching the tunnel, and assume atmospheric pressure at theoutlet section of the tunnel. Assume α=1.0 at alllocations.
Also, the propellor is situated at the end of the tunnel wherethe area is 10 m2 (rigth before the tunnelis opened to the atmosphere). So I used the energyequation, but I have two unknows: pressure P of thetest section, and the shaft work hT orhP (I am not sure if it is a pump or aturbine).
Create a precedence (activity-on-node) diagram based off the attached activity list. You must follow the below recommendations as we discussed in class. 1) draw nodes as rectangles. It helps define the left side as starting and the right side as en..
A heavy Machine is lowered into a pt by means of a rope wrapped around an 8" diameter stationary pole placed horizontally across the top of the pit. The coefficient of static friction for the rope on the pole is 0.35.
if the resultant of the 1000 lb vertical force and the tensile force T in the cable is to be in the direction of the boom OB, what must be the magnitude of T
A three span continuous beam has spans of 27, 30, and 27 feet. The beams support one-way slabs, 6 inches thick that span 20 feet center to center. Assume that the beams are 16 inches wide and 24 inches deep.
Describe the equation for charging a water tank. Use: H= 2m, A_s = 1m^2, density water = 1000kg/m^3, K = 2000kg hr^-1 Mass flow in = K t. Calculate how long will it take to charge completely the tank
The vertical post is secured by three cables. The cables are pre-tensioned so that the resultant of the cable forces F, Q, and P is directed along the z-axis. If F =120lb, find P and Q.
At compressor exit, the specific entropy is the same as that at the inlet, and the pressure is 60 psia. Determine the R-134a exit temperature and the change in the enthalpy of R134a.
Assume the ledge has the dimensions shown and is attached to the building with a series of equally spaved pins around the circumference of the building.
Determine the required dimensions. The inside diameter is to be two- thirds of the outside diameter. The allowable shearing stress is 70 MPa, and the angle of twist is not to exceed 4 degree in 3 m of the shaft.
The density of an ideal gas decreases by 10% when compressed isothermally from 10 atm to 11 atm. Determine the percent decrease in density of the gas if it compressed isothermailly from 1000 atm to 1001 atm.
If clean groundwater flows through an aquifer contaminated with a dense non- aqueous phase liquid (DNAPL), calculate the concentration of DNAPL in the water as a function of time if the DNAPL is dissolving into the water at a rate of k1
