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)

ISSUES ANALYSIS: You should prepare a brief (350 – 500 words) analysis of an issue relevant to Macroeconomic. Pick a topic. The purpose of these analysis assignments are to analyze a current issue. To do this, you should obtain a news article from a reputable news source, and conduct an analysis of the topic.

a. An unsymmetrical I section prestressed concrete beam of top flange (350 X 40 mm) in size, bottom flange of (200 X 40 mm), 30mm thickness of web and overall depth of 400 mm is prestressed with 19 numbers straight steel wires of 7 mm diameter located at a distance of 15 mm from the bottom of the soffit and 9 numbers of straight steel wires of 6 mm diameter located at a distance of 15 mm from the top of the beam. The wires were initially tensioned on the prestressing bed with an initial prestress of 1.2 + 0.01 (54) GPa. The length of the beam is 10 m. Calculate the total percentage loss of stress in the wires at top and bottom. Assume the beam is post tensioned beam and all the wires stressed simultaneously by using the following data: Relaxation of steel stress= 4.5% of initial stress -6 Shrinkage strain in concrete for post tensioning = 200 x 10 Creep Coefficient ɸ=1.6 Friction coefficient for wave effect=0.0015 + 0.001 (54) per meter Slip at anchorage= 1.5 mm Modulus of elasticity for steel = 210 GPa Modulus of elasticity for concrete= 35 GPa

b. What are the measures that are suggested to be taken to reduce the losses in prestressed concrete members for the above problem?

Please help. I have been sick all week and having trouble finding the energy to get all my course work done. Also, I need it to include at least one reference.

5.One kilogram of superheated steam at 350°C and 20 bar absolute pressure are sealed in a rigid container. Cold water is sprayed on the container until the temperature is 50°C. (Remember that the container is rigid, so the total volume doesn’t change.) a) What is the volume of the container in liters? (Do not assume ideal gas behavior.) Liters b) Is the correct energy balance for this problem based on energy or enthalpy? (answer either enthalpy or internal energy) c) What is the final pressure inside the container (in Pascals)? Pa d) How much of the initial water condenses (g), if any? g e) How much heat was removed from the container while it was being cooled (kJ)? kJ f) How much work was done while the container was being cooled (kJ)? kJ.

A particular power plant operates with a heat-source reservoir at 350°C and a heat-sink reservoir at 30°C. It has a thermal efficiency equal to 67% of the Carnot-engine thermal efficiency for the same temperatures.

What is the thermal efficiency of the plant?

The thermal efficiency of the plant is  .

Question 4

The stock of ABC Inc is trading at $50. You short sold 350 shares of ABC at this price. However, price increased to $55, at which point you decided to close the trade. What was your percentage return? The initial margin rate is 75%.

Question 5

Consider the short sale trade in the previous question. If your brokerage requires a maintenance margin of 40%, at what price will you get a margin call? The initial margin rate is 75%.

Question 6

You find that in a normal year, the S&P500 index gives a return of 12%. However, you think that there is a 40% probability of the economy going into recession next year. If that happens, you predict that the index return will be 2%. What is the expected return on the S&P500 next year?
