b. 145 C

c. 98.6 F

4. Convert the following temperature intervals to Kelvin.

a. 58.3 C;

b. 89.7 F;

c. 4.5 R;

5. A weir is a slot in an open channel with water flowing over it (Figure 14.12). For a weir with a rectangular shape, the following formula can be derived:

Q = 5.35 Lh^(3/2)

Where

Q = water flow rate. ft3/s

L = length of weir, ft

h = height of liquid above weir gate, ft

Do the following:

a. Determine the units associated with the constant that are needed to make the equation dimensionally homogeneous.

b. Determine a new constant that allows the following units to be used:

Q = water flow rate, gal/min

L = length of weir, ft

h = height of liquid above weir gate, in
