A Pitot tube with a yaw angle of 10? is used for the airflow in Prob. 7.39. What would be the indicated stagnation and dynamic pressures? Express in units of Pa, lbf/in2, and inH2O.
Prob. 7.39
An open-ended stagnation pressure probe is inclined at a yaw angle of 20? with the flow velocity. For airflow at 20 m/s, 1 atm, and 20?C, what would be the indicated pressure?
Estimate how much carbon (in pounds) must be purcahsed for a typical 2-bed carbon adsorption system to treat 5000 cfm of air at 95 degrees F and 1 atm. The air contains 600 ppm of styrene.
How far apart must two 18 m diameter tanks be placed such that their stress overlap is not greater than 10% of the contact stress at depths of 10, 20, and 30 m
A commuter train has stations spaced 1 mi apart. The top speed of the train is 80 mph. The train accelerates at 5.5ft/sec2 and decelerates at 4.5 ft/sec2. It dwells at the platform for 20 sec to pick up passengers.
A circular bar under pure torsion needs to transfer 50 N*m of torque. The total bar length is 1 m and the total rotation can not exceed 2 degrees. The bar is made of a material with G=3000 MPa.
The melting point of lead is 620 F, and the enthalpy change between the phases hif is 10.6 Btu/lbm. The specific heats are found in Table F.2 and F.3. Calculate the net entropy change for the lead.
What is the theoretical maximum amount of work that could be done by a gas in a piston expanding from 10 L to 20 L (pressure of the surrounding atmosphere is 100 KPa)? What assumptions do you have to make to achieve this theoretical maximum? How much..
The subway train is traveling at a speed of 54 km/hrwhen the brakes are fully applied on the wheels of cars B and C,causing them to slide on the track, but are not applied on car A.μ of kinetic friction= 0.35.
If variable Test(i,j) is selected so the first column represents the student number (1,2,..., 32), 2nd column represents the score of the first homework, 3rd column represents the score of the 2nd homework, etc.
The scholarship will provide a student with an annual stipend of $2500 for each of 4 years (freshman through senior), plus an additional $5000 during the senior year to cover entertainment expenses.
(i) Determine the flow rate through pipe B. Discard minor losses and assume the water temperature to be 150C. (ii) Show that the flow is fully rough and thus the friction factor is independent of Reynolds number.
given: Vf=Vi + a t and Sf=Si + Vi t + 1/2 a t a= 27 ft/sec^2 accelerates from 10 mph to 93 mph in 4.5 seconds designers decided to modify the rise to become the tallest roller coaster in the world, find final velocity in mph if the drop height is ..
