Why do we need light weight blocks and define its benefits based on its various properties it possess?

A rectangular detention basin will be connected to outlet of the above drainage system to reduce the peak flow rate to 5m³/s. Determine the dimensions of the basin if the length of the basin is 3 times of the width. An orifice will be used as the outlet of the basin and the depth of water above the center of the orifice should be less than 2m. What is the size of the orifice?

Describe briefly the principle of the Rational method and the limitation of this method for runoff estimation. A sub-catchment of area 0.1km² is built on gently sloping land. The average slope of the land is 0.001. The length of the longest natural flow path L is 276.3m. The flow time t_f in the drainage system is 3min. Determine the 50yr design discharge for the subdivision using the rational method, given that the average runoff coefficient of the subdivision is C=0.7.

The above sub-catchment is drained by a pipe system which is also used to drain the second sub-catchment. The second sub-catchment is of area 0.2km², average slope 0.002, L=300m, and t_f=3min, C=0.5. If the pipe system is designed for the 50-yr rainfall event, what is the appropriate duration to be used? Explain briefly. Hence determine the 50yr design discharge of the drainage system.

The 50-yr rainfall intensity i can be calculated from i(mm/hr)=a/(td+b)^c, where a=687, b=4.2, c=0.42, t_d(min)=duration.

Engineering student Bryan has a high-paid summer job as a forklift operator. This job enables him to attend college without having to take out any student loans. He is now staring at a 50- gallon drum filled with used machine coolant, wondering what he should do.

Just moments ago, Bryan’s supervisor, Max, told him to dump half of the used coolant down the drain. Knowing the coolant was toxic, Bryan noted this to Max, but Max was not swayed.

Max: The toxins settle at the bottom of the drum. If you pour out half and dilute it with tap water while you are pouring it, there is no problem.

Bryan: I don’t think that’s going to work. Besides isn’t it against the law?

Max: Look, kid, I don’t have the time for chitchat about a bunch of silly laws. If I spent my time worrying about every little regulation that comes along, I’d never get anything done – and neither will you. Common sense is my rule. I just told you – toxins settle at the bottom, and most of them will stay there. We’ve been doing this for years, and nothing’s happened.

Bryan: You mean not one’s said anything about it? That doesn’t mean the environment isn’t being harmed.

Max: You aren’t one of those “environmentalists”, are you? You college guys spend too much of your time in the “ivory tower.” It’s time to get real – and get on with the job. You know, you’re lucky to have a good-paid job like this, kid. In three months, you will be back in your cozy Page 2 of 3 college. Meanwhile, how many other college kids do you think are out there wondering if they’ll be able to afford to go back – kids who’d give their eyetooth to be where you are right now.

Max then left, fully expecting Bryan to dump the used coolant. Bryan stared at the drum, he pondered his options. What options do you think he has? Conduct an ethical analysis of the above case.
