Water enters a circular tube whose walls are maintained at constant temperature at specified flow rate and temperature. For fully developed turbulent flow, the Nusselt number determined from Nu - 0.023 can be law of cooling in this case is Re0.8 PrO.

The correct statement about the relation between the shear stress (force) at the surface for laminar and turbulent flow over a flat plate is. a. The laminar shear stress is greater because the fluid viscosity is not important in turbulent flow. b.

Suppose you have the following function prototype and variable declaration: public void goop (int[ ] z) int[ ] x = new int[10]; Which is the correct way to call the goop method with x as the argument: (A) goop (x); (B) goop (x[ ]); (C) goop (x[10]);

Opposition to current flow, restricts or resists current flow A) voltage B) current C) resistance

If the open circuit voltage of a circuit containing ideal sources and resistors is measured at 6 V, while the current through the short circuit across the circuit is 200 mA, what would be the power absorbed by an ideal current source, I_s =

Given an unsorted array of distinct positive integers A[1 ... n] in the range between 1 and 10000 and an integer i in the same range. Here n can be arbitrary large. You want to find out whether there are 2 elements of the array that add up to i.
