7. A stormwater system is designed to handle 25-year runoff events. Cal culate the probability that over a six year period, the system experi- ences two episodes that exceed the design levels
Q15) A radio transmission tower is designed for a "50-year wind", that is, a wind velocity having a return period of 50 years. (a) What is the probability that design wind speed exceed for the first time in the fifth year after completion of the structure? (b) What is the probability that design wind speed occur within 5 years after completion of the structure? (c) What is the probability of exactly one 50-year wind in 5 year?
An offshore structure with a design life of 20 years is planned for a site where extreme wave events may occur with a return period of 100 years (i.e. the 100-year wave). The structure is designed to have a 0.99 probability of not suffering damage within its design life. Damage effects between wave events are statistically independent (a) You found in HW 4 that the yearly probability of exceedance of the design wave height is p = 1/100 = 0.01....
Design of Agitation System. An agitation system is to be designed for a fluid having a density of 950 kg/m3 and viscosity of 0.005 Pa · s. The vessel volume is 1.50 m^3 and a standard six-blade open turbine with blades at 45°C (curve 3, Fig. 3.4-4) is to be used with Da/W = 8 and Da/Dt= 0.35. For the preliminary design a power of 0.5 kW/m3 volume is to be used. Calculate the dimensions of the agitation system, rpm,...
8- You are planning to save for retirement over the next 15 years. To do this, you will invest $1,100 a month in a stock account and $500 a month in a bond account. The return on the stock account is expected to be 7 percent, and the bond account will pay 4 percent. When you retire, you will combine your money into an account with a 5 percent return. How much can you withdraw each month during retirement assuming...
The average return on mid-cap equities was 11.9% over the past 50 years. If the average return on Treasury bills was 3.1% over that period, what was the risk premium for mid-cap stocks?
An investment of $10,000 in a high risk venture has a 50-50 chance over the next year of increasing to $14,000 or decreasing to $8000. Thus the net return can be either $4000 or -$2,000. Two investors A and B have exhibited the following indifference probabilities: Indifference Probabilities Net return ($) Investor A Investor B -2000 0.00 0.00 -1000 .70 .10 0 .80 .20 1000 .85 .30 2000 .90 .50 3000 .95 .60 4000 1.00 1.00 Graph the utility functions...
you are planning to save for retirement over the next 15 years to do this you will invest $700 a month in a stock account and $400 a month in a bond account. The return of the stock account is expected to be 10 precent and the bond account will pay 6 precent. When you retire, you will combine your money into an account with a 8 precent return. How much can you withdraw each month from your account assuming...
JBL Co. has designed a new conveyor system. Management must choose among the three alternative courses of actions : (1) The firm can sell the design outright to another corporation with payment over two years (2) It can license the design to another manufacturer for a period of 5 years, it it likely product life. (3) It can manufacture and market the system itself; this alternative will result in 6 years of cash inflows. The company has a cost of...
(b) A schematic diagram of a simple transport system designed to transport oil over a lon distance. A schematic diagram of the system is illustrated in Figure 3(b). The elevations of free surfaces of tanks 1 and 2 from a common ground level are measured to be 100 m and 145 m respectively. The tanks are connected with 300-m long a circular pipe of diameter 50 cm The supply curve of the pump connected is given in Figure 3(c) Express...
