a). Explain how the presence of the collimation error, "e" can be detected in a "Two Peg Test" operation.b). A, B and C are three points on line, such that AB = 90 metres and BC = 70 metres. A leveling instrument is set up at I1 and I2 on line AB, such that AI1 = 30 metres, and I2B = 30 metres.The data below was then collected.I.S S.S S.R(m) RemarkI1 A 2.040 uprightI1 B 1.881 uprightI2 A 3.222 uprightI2 B 3.183 uprightI2 C 3.003 inverted1). Determine the collimation error, e, present in the instrument.2). Calculate the uniform slope of line AC in the form 1 in N.
Which of the following is not a basic systems engineering concept?a. Define need before function
Assume the rate constant for BOD decay is 0.2 d^-1, the mean velocity of the stream is 0.5 m s^-1, and the initial concentration is 100 mg L^-1 at x=0. Plot the resulting concentration with downstream distance x in km.
The pipe contains two 6 in steel elbows, two fully open gate valves, a fully open 90o angle valve, and a swing check valve. If the discharge end of the pipe is located 20 ft higher than the entrance, what is the pressure difference between the two..
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.
How many short tons of coal are required by this plant per year, assuming it operates continuously? If 10% of the coal mass remains as residual ash, how many tons will develop in the ash pile over 25 years?
a. Determine the shear and moment diagram. b. Calculate the maximum normal stress on the top of the beam, on the bottom of the beam and indicate in terms of x its location.
Discuss bracing types of buildings with real-life example. Provide photograph or sketch for each type of bracing.
Hardness is sum of all divalent cations (meaning all species with a positive charge of 2) in a water sample. Magnesium (Mg2+) and calcium (Ca2+) are the most common divalent cations that contribute to hardness.
a mountain water reservoir in a national park is to provide water at a flow rate of Q= 200 gpm and a minimum pressure of 40 psig in the lodge of the valley 200 ft below the reservoir.
Estimate the diameter of the tower, based on bottom operating conditions. Assume that the density and viscosity of the bottom liquid are the same as tose for pure water. Make other appropriate assumptions as needed.
Determine the Stoichiometric oxygen requirement (pounds of oxygen per pound of fuel) for a fuel containing by weight 50% n-octane,25% 1-heptene and 25% methanol.
Diesel fuel has an average chemical formula of C12H23 and a density of 6.45 lb/gal. Calculate how many lbs of CO2 are produced per gallon of diesel burned (assume complete combustion).
