Type a statement using srand() to seed random number generation using variable seedval. then type two statements using rand() to print two random integers between (and including) 0 and 9. end with a newline. ex: 5 7 note: for this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). use two statements for this activity. also, after calling srand() once, do not call srand() again. (notes)

rand(), srand() and seeding of values are all illustrations of generating random numbers in C++.

The first statement using srand() is:

srand(seedVal);

The other two statements to generate and print random integers between 0 and 9 are:

cout<<rand()%10<<endl; cout<<rand()%10<<endl;

The first statement

The syntax of the srand() instruction is: srand(variable);

From the question, the seeding variable is seedVal.

So, the statement that implements the srand() instruction will be:

srand(seedVal);

The other two statements

The other statements are to generate and print random numbers between 0 and 9.

The syntax to generate random numbers between intervals in C++ is:

$lower + rand() \% (upper - lower + 1);$

From the question;

$lower = 0\\ upper = 9$

So, we have:

$0 + rand() \% (9 - 0+ 1)$

This becomes

$rand() \% (10)$

The above statement represented the random number that has been generated.

Next, is to print the numbers (this is done using cout statement).

So, the two statements to print the random numbers are:

cout<<rand()%10<<endl;

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
