A subsonic airplane is flying at a 3000-m altitude where the atmospheric conditions are 70.109 kPa and 268.65 K. A Pitot static probe measures the difference between the static and stagnation pressures to be 35 kPa. Calculate the speed of the airplane and the flight Mach number
A 1200 ft. equal tangent crest vertical curve is currently designed for 50 mi/hr. A civil engineering student contends that 60 mph is safe in a van because of the higher driver’s eye height. If all other design inputs are standard, what must the driv..
At that time, the rocket has reached an altitude of 500 m and is rising at a velocity of 125 m/s. Gravity then takes over. The height of the rocket as a function of time is Create a function called height that accepts time as an input and returns..
A rod of steel is 20 m long at a temperature of 200C. find the free expansion of the rod when the temperature is raised to 65 0 C. Find the temperature stress produced
The foof of the culvert will be located 3 m below ground surface. Currently the groundwater level is at ground surface. But, after installation of the culvert, the groundwater level is expected to drop 2 m below ground surface.
The cross-sectional area of the sample was 60 cm2 and its length was 150 mm. For 80 cm3/min steady-state flow rate, a total head difference of 8 cm was measured across two points separated by 10 cm along the axis of the sample.
If the BOD5 of a municipal wastewater is 310 mg/L and the BODU is 340 mg/L, determine the BOD reaction rate constant (base e). What would be the 3 day 30°C BOD Assume, temperature coefficient = 1.047.
During that same hour, 20 departing aircraft uniformly arrive at the runway within a 20-minute period. Assume no other departing aircraft arrive at the runway during the hour.
A round bar of 6mm diameter is made of 6061-T6 aluminum. When the bar is stretched by an axial force P, its diameter decreases by 0.450 microns. what is the magnitude of the load P
Cork is used for sealing sparkling wine bottles. Aside from friction, why not use rubberbto seal wine bottles. (Hint: think about the force exerted by the pressure inside and how does that deform each material) Be sure to use poissons ratio in the..
Reservoir A (water surface elevation = 1300 ft) is connected to reservoir B (water surface elevation=250 ft) by 6,000 ft of 14 inch diameter cast iron pipe (e = 0.005 ft. Neglecting all minor losses
What are the expressions for the shear, V, and the bending moment, M, within the beam between points C and D in terms of Ay, M1, l, w, and x, the distance to the sectional cut from the beam's left end?
An object which has a volume of 0.18 m^3 requires a force of 265 N to keep it immersed in water. If a force of 157 N is required to keep it immersed in another liquid, find the specific gravity of the liquid
