Comment on sources on uncertainty in culvert design and how would an engineer manage these uncertainties

In an air conditioning system, the inside and outside conditions of air are 25 °C DBT and 50%
RH, and 40 °C DBT and 27 °C WBT, respectively. The room sensible heat ratio is 0.8, while
50% of the room air is rejected to atmosphere and replaced with an equal quantity of fresh air
before entering the air conditioning apparatus. If the fresh air added is 100 m3
/min and the air
density is 1.2 kg/ m3 with zero air by-passing, determine: a) Room sensible and latent load, b)
Sensible and latent heat due to the fresh air, c) Apparatus due point, d) Humidity ratio and dry
bulb temperature of the air entering to the air conditioning apparatus. Ans. a) 53.96 kW,
14.04 kW; b) 30.67 kW, 39.73 kW; c) 11.8 °C; d) 0.0138 kg/ kg dry air, 32.5 °C

A large stream with a velocity of 0.85 m/s, saturated with oxygen, has a reoxygenation constant k2 = 0.4 day−1 and a temperature of T = 12oC, with an ultimate BOD = 13.6 mg/L and a flow rate Q = 2.2 m3 /s. Into this stream flows a wastewater stream with a flow rate of 0.5 m3/s, T = 26oC, L = 220 mg/L and oxygen level = 1.5 mg/L. Downstream the deoxygenation constant is k1 = 0.2 day−1 .

a) What is the dissolved oxygen 48.3 km downstream?

b) What will be the minimum dissolved oxygen? And at what distance from the outfall?

A concrete mix was designed for thin core walls in a tall building. A 28-day strength of 32 MPa is required. The exposure classification for durability purposes is for B2 and C. One hundred laboratory test results on the controlling mix show a standard deviation of 5.3 MPa (k=1.65). The density of uncrushed coarse aggregate is 2850 kg/m³ and its dry rodded density is 1600 kg/m³ and the maximum size to be used is 10 mm. The density of fine aggregate is 2750 kg/m³ and its fineness modulus is 3.0. The high early strength cement used has a density of 3150 kg/m³.

Find the weight (in kg) of cement, water, fine and coarse aggregate for this mix, required to make a 2.4 m high x 1.2 m wide x 120 mm thick concrete wall using the ACI Method.                                                                                            

Water flows at a rate of 6m^3 / s in a rectangular channel of 3m width and 60cm water depths . Check whether the hydraulic jump occurs or not . If it is occurred , then determine the total energy loss during the jump and the jump efficiency . What is the type of this jump ?

Performance of Reinforced Concrete Slab due to Reinforcement Corrosion

If a cylindrical steel pressure vessel has a 400-mm inner radius and 8-mm-thick walls. Find the change (mm) in the inner radius when the vessel is pressurized to 1.2 MPa. Use E = 200 GPa and v = 0.3 for steel.

It is believed that the design of appurtenances in the stilling basin can reduce the basin length by 70- 80%. Give comments on this statement.

What does it mean for a professional to uphold a standard of due care? What norms and standards should an engineer look to, in determining what constitutes "due care" in a given situation? Why is it hard to have universal and precise rules that tell us exactly what "due care" requires in a given situation? How does an engineer know the difference between practicing due care, and being negligent?
