What is the distance between the face represented by line E and the surface represented by line S?
A jet engine receives a flow of 500 ft/s air at 10 lbf/in.2, 40 F, inlet area of 7 ft2 with an exit at 1500 ft/s, 10 lbf/in.2, 1400 R. Find the mass flow rate and thrust.
How can a manager effectively balance the key components of a Six Sigma implementation design related to who, what, where, when, why and how it could be done?
For two 0.2 m long rotating concentric cylinders, the velocity distribution is given by u(r) = 0.4/r - 1000r m/s. If the diameters are 2 cm and 4 cm, respectively, calculate the fluid viscosity if the torque on the inner cylinder is measured to be 0...

1. 260 watts of electrical power consumption. 2. External temperature (cooling air inlet temperature) = 77 degrees Fahrenheit 3. Safety (touching) specification (cooling air outlet temperature) = 100 degrees Fahrenheit 4.
determine the stress components at points D and E . Show the results on a differential element located at each of these points. Take F = 12 lb and θ = 90°.
In a certain chemical plant, a closed tank contains ethyl alcohol to a depth of 50 ft. Air at a pressure of 25 psi fills the gap at the top of the tank. Determine the pressure at a closed valve attached to the tank 10 ft above its bottom.
An industry is illegally dischargingbenzeneinto a river. The concentration in the river atthe point of discharge is 0.2mg/L. A drinking water treatment plant (DWTP) is located 1.5km downstream. The watervelocity in the riveris 0.35km/day.
A municipal WWTP discharges 22.5 MGD of secondary effluent containing 45 mg/L of ultimate BOD at 26.7 oC with 1.3 mg/L of dissolved oxygen. The stream flow is 237 ft3/s at a velocity of 2.1 ft/s and an average depth of 7 ft.
Two solid rods AB and BC are welded together at B and loaded as shown. Knowing that d1=50mm and d2=30mm, find average normal stress at the midsection of rod AB and rod BC.
An engineer is to design a channel lined with planed wood to carry 2 m3/s of water on a given slope. The channel cross section can be either a 90 degree triangle or a square. Which would require less wood and by what percentage
Determine the force at the circular endcap and its location relative to the bottom of the pipe. If there is a hinge at the bottom, what external force would need to be applied to the top to prevent rotation
