As per the statement of one of my friend, he can drop kerosene to diesel and treat the entire quantity in a big HDS (diesel hydro-treater) and make Euro IV / V Diesel.

Is it possible? What about the quality of Diesel in this case? Will HDS make things alright ?

Here the Kerosene availability is so high and they make Jet A1 and if the demand for it is not there, they want to make Diesel out of it?

Can anyone help teach me this aspect

A valve in a full 6000 gallon water tank is slowly opening. Water flows out of the tank through the valve. The flow rate in gallons per hour is given by the function where t is in minutes. How much water flows out of the tank in the first 8 minutes? How many minutes does it take for the tank to empty completely?

A quartback throws the football to a stationary receiver who is 31.5 m down the field. If the football is thrown at an initial angle of 40 degrees to the ground, at what initial speed must the quartback throw the ball for it to reach the receiver? What is the ball's highest point during its flight?


Please show your work so I'll have an idea of what is going on.

then the instantaneous velocity at a height = (1/2)the maximum height,is u [(1-(sin^2 X)/2)]^(1/2) (i,e product of initial velocity and the square root of the difference of 1 and half the square of sine of the angle of projection). Now the question is that,as the horizontal velocity of a projectile is constant,the cosine component of this instantaneous velocity should give the horizontal velocity i,e
u cosX.But where does it ?I am unable to convert the expression of ins. velocity to u cosX.Please help

In how many ways can Kurt, Andrew, and John distribute 12 beers amongst the three of them? Assume it is possible for Kurt and Andrew to get 0 and John to get all twleve. But since Kurt is the biggest, Kurt will get at least 3 of the 12 beers.
Also, what is the probability Kurt will get at least 3 of the beers?

Hello, I'm new to context free languages and having trouble converting from a mathematical description of a language into the CFG syntax. For example, if I'm asked to find (a^n)(b^n) for n greater or equal to zero, that is a language that has the same number as a's as b's that begins with "a", i know that I can write the context language as:
S-->aSb | e

How do I handle a situation where I have something like:
(a^m)(c^p)(d^q) such that m = p + q.

Anyone have an idea??
Thanks

A couple years ago, the temp was 20 degrees outside. I checked the thermometer. I don't know why i waited this long to post this question. It just came to me. Anyway, the temp outside was 20 degrees, and it was pouring down rain and thundering and lightning. I am not kidding. It was one heck of a thunderstorm. This was around 9 o'clock that night. I remember it well because i have never seen it rain like that at 20 degrees. I live in southeast VA if that will help any. Why did it rain and not snow? Has anyone else ever seen anything like this?

Things to exclude:
5 Holidays / yr.
13 days vacation off first 5 years, 18 days years 5 through 14, and 23 days off years 15 through 17. Plus an average of 5 sick days per year.
