Homework Help: math

Posted by Pleasehelp! on Monday, October 26, 2009 at 9:51pm.

In a measurement of precipitation (rainfall), a raingauge with an orifice (collector) area of 30.50 in2 collects 1.30 litres of water over a period of 26 minutes and 45 seconds.[10]

Calculate:
1) The depth (amount) of rain that fell (in mm).

2) The intensity (mm h-1) at which the rain fell.

3) The volume (m3) of water that would have fallen on an area of 7.00 acres.

4)The discharge in m3 s-1 that would occur if all the water ran off the area in part c. in 3.00 hours.

5) If American gasoline is US$4.00 gallon-1, how much is that in CAN$ L-1?

conversions!
1 ha = 104 m2 (a hectare {ha} is an area 100 x 100m);
1 m = 3.2808 feet,
1 km2 = 106 m2 (103 x 103) m2;
1 inch = 25.4 mm;
1 m = 1000 (103) mm,
1 (inch) = 2.54 cm,
1 (Canadian) gallon = 4.55 L,
1 (American) gallon = 3.785L,
1 L = 1000 cm3,
1 mile = 5,280 feet,
1 mile2 = 640 acres
