A Tank with a dimension of length (L) x width (B) x height (H) of 4m x 2m x 2m is filled with 1m depth of water and with oil to the fullest. Density of oil ρm= 801 kg/m3. The tank is open.
1.Calculate and draw pressure distribution on tank wall
2.Calculate force on the length and width side of tank wall, also on the bottom of the tank Given: ρwater= 1000 kg/m3 , g = 9,81 m/sec2

Water in pipe AB (Figure 2), diameter (DAB) 1.2 m, is flowing with the velocity (VAB) of 3 m/second. Then it continues to flow through pipe BC, with a diameter (DBC) of 1.5 m and finally flows through branch pipe of CD, diameter (DCD) of 0.8 m and pipe of CE (DCE), with a velocity (VCE) of 2.1 m/second. Calculate:
1. Discharge of pipe AB (QAB)
2. Flow velocity of pipe BC (VBC)
3. Flow velocity of pipe BC (VBC)
4. Diameter of pipe CE (VCE)

4a. A water authority has decided to procure a new water treatment station by design and build. Identify and discuss the information you would advise the Client to provide for inclusion in the Contract Data

4b. What information should tenderers provide for inclusion in the Contract Data?

6 A car is traveling at 20 mi/h on good, dry pavement at 5000 ft elevation. The front-wheel-drive car has a drag coefficient of 0.30, a frontal area of 20 ft2 and a weight of 2500 lb. The wheelbase is 110 inches and the center of gravity is 20 inches from the ground, 50 inches behind the front axle. The engine is producing 95 ft-lb of torque and is in a gear that gives an overall gear reduction ratio of 4.5. The radius of the drive wheels is 14 inches and the mechanical efficiency of the drivetrain is 90%. What would the acceleration of the car be if the driver was accelerating quickly to avoid a collision? a) 3.65 ft/s2 b) 15.53 ft/s2 c) 15.90 ft/s2 d) 3.48 ft/s2

Please describe about an Evapotranspiration in Indonesia (you can choose the location). The paper must be including:

- climate condition
- how to determination the evapotranspiration
- please find the climate data (from BMKG) and calculate the potential evapotranspiration.

A long, straight horizontal pipeline of diameter 350 mm and effective roughness size
0.03 mm is to be constructed to convey crude oil of density 860 kg/m3 and absolute
viscosity 0.0064 N s∕m2 from the oilfield to a port at a steady rate of 7000 m3/day.
Booster pumps, each providing a total head of 20 m with an overall efficiency of 60%,
are to be installed at regular intervals. Determine the required spacing of the pumps and
the power consumption of each. (ans. 8700 m and 22.78 kW) (I need a precise answer please)

• Discuss the importance of Density-Strength Ratio of different construction materials and its effects on the properties of the structure.

What characteristics of aluminium and mild steel make a difference in resilience and toughness?

- Considering chemical composition for each.

why Ultimate tensile strength and ductility are important factors

Define rework in construction project and milestone in construction project and give example .

Sketch a ring-barrier diagram for a signalized intersection which shows eastbound and westbound
with permissive lefts concurrent with the through movements (single ring) while northbound and
southbound have leading left protected (2-ring) phasing. Clearly annotate your diagram using
standard NEMA numbering, omit right turn movements, label the rings and the barriers.
