3. An oil well contains water at the bottom, oil floating on it, and air above the oil. You performed
two time-of-arrival measurements with an instrument that measures the depth of the well using
a light beam. The first reading on the instrument is t1= 1.33us and the second one is
t2= 1.29 us taken after a certain amount of oil was pumped out.
Calculate the change in the oil level considering the oil refractive index 1.46.

State whether the followings are True or False? (1) The angle of internal friction can vary from 0 to 90˚ since it is an angle. (2) A degree of saturation of 40% implies that 40% of the total volume consists of water. (3) Clays can have both cohesion and angle of internal friction. (4) In the triaxial test the horizontal plane is the major principal plane. (5) Piping (failure due high exit hydraulic gradient downstream) starts upstream and then progress to downstream face of a concrete dam. (6) It is safe to say that: in general natural soils in the field have larger permeability in the horizontal direction than the vertical direction. (7) Due to consolidation ∆? ?????????,?ℎ?? ? ?????????. (8) Consolidation is process of reducing voids by removing water and air if present. (9) In seepage in two dimensional impervious boundaries are equipotential lines. (10) Lowering the ground water table will increase the shear strength of the soil. (11) Due to consolidation the effective stress will increase. (12) Increasing the water pressure head at both upstream and downstream by 1 m will reduce piping.

The state government of Perak has recently announced the building of a suspension bridge between Pulau Pangkor and Peninsular Malaysia. The construction cost of the bridge is estimated at RM100 million and this 4-lane bridge will take approximately 3 years to complete. This infrastructure project is expected to encounter many technical challenges and require the involvement of various parties, particularly engineers of different disciplines and expertise. Predict engineering-related ethical issues that may possibly occur during the construction of the suspension bridge. Discuss on the root causes of each ethical issue you have identified. Finally, propose the efforts that can be duly taken by a professional engineer to prevent the ethical issues you have mentioned.

fluid mechanics lesson (calculating popa power)

Calculate the power of the pump required to pump the water in hp (1 BG = 550 lbf.ft / sec)? Density = 62.4 lbm / ft3 and Viscosity = 1 cp. Water can send to a tank on a flow rate of 30 ft3 / min. data: g = 32.2 ft / sec2, gc = 32,174 lbm.ft / lbf.sec2, T = 20 degrees Celsius, Pump efficiency = 0.80.

Pipe (2) is supported by a pin at bracket C and by tie rod (1). The structure supports a load P at pin B. Tie rod (1) has a diameter of 10 mm and an allowable normal stress of 110 MPa. Pipe (2) has an outside diameter of 54 mm, a wall thickness of 6 mm, and an allowable normal stress of 165 MPa. Assume x1 = 3.6 m, x2 = 1.2 m, and y1 = 3.5 m. Determine the maximum load Pmax that can be supported by the structure without exceeding either allowable normal stress.

ENVIRONMENTAL QUALITY ENGINEERING 1- CE 364
ASSIGNMENT 1-14th May, 2020
Provide a flow diagram for a typical community water supply system. Describe each of the complements mentioned

Ghana Water Company Limited delivers an annual quantity of 15,000,000 m3 to KNUST of 100,000 consumers. At the same time, the collected revenue is GHS 6,000,000, at an average water tariff of GHS 0.5/m3 . Determine:
a the delivery on an average consumption day
the percentage of unaccounted-for water
the specific consumption per capita per day, assuming 60% of the total delivery is for domestic use.

A family of four pays for annual water consumption of 185 m3 . Determine:
the specific consumption per capita per day
the instantaneous peak factor at a flow of 300 l/h.

Accurate forecasting of water demand for a city is crucial to ensure satisfactory performance of water distribution systems. Discuss five (5) factors that may affect water demand.
