1.A Parshall flume with a throat width of 2.50 feet is used to measure discharge.  If the measured depth, H, is 1.8 feet, what is the discharge? Need to know how to solve for the discharge.

2.A rear wheel drive 3000 lb drag race car has a 200 inch wheelbaseand a center of gravity 20 inches above the pavement and 140 inchesbehind the front axle. The owners wish to achieve an initialacceleration from rest of 15 ft/s2 on a level paved surface. What is the minimum coefficient of road adhesion needed to achieve thisacceleration? (assume γm=1.00)

From this I know that W=3000

L=200

h=20

lf=140

a=15

How to find μ, given acceleration?
