A hydrograph has a uniform rainfall intensity of 1.5 in/hr in the first hour, 2.0 in/hr in the second, and 0.75 in/hr in the third hour. Direct runoff (in inches) using the SCS method is 1.2in. Assume a curve number of 65. Determine the peak discharge if the unit hydrograph is triangular with a time to peak of 2 hours, base time of 6 hours, and drainage area of 250 (in cfs).
What are the velocities of both just before impact and just after impact. There is a distance of 5m between the vehicles prior to the winch being turned on.
A steady-flow compressor is used to compress helium from 15 psia and 70oF at the inlet to 200 psia and 600oF at the outlet. The outlet area and velocity are 0.01 ft2 and 10 ft/s
Assume a cross-sectional medial length of 32 in. (no stretching of the sheet due to bending). If the maximum shear stress must be limited to 19 ksi, determine the maximum torque that can be carried by the hollow section
a silty material is to be used to fill an earth damn. How much water must be added to bring the water content of each ton (2000 lb) of the material to 35% if the original watter content is 11.4%
A second load P2 is uniformly distributed around the cap plate at B. The diameters and thicknesses of the upper and lower parts of the post are dAB= 1.25 in, tAB= 0.5 in, dBC= 2.25 in and tBC= .375 in respectively.
Determine the height "h" on the wall to which the firefighter can project water from the hose...and the speed of the water at the nozzle is v= 55ft/s. The firefighter is holding the hose 3.5 ft from the ground and the wall is located 15ft from the..

The mass of each pulley of the system is 50 kg, and mass of the suspended object A is 160 kg. Determine the force necessary for the system to be in equilibrium? Be sure to draw complete free body diagram(s) for full credit.
An industry is illegally dischargingbenzeneinto a river. The concentration in the river atthe point of discharge is 0.2mg/L. A drinking water treatment plant (DWTP) is located 1.5km downstream. The watervelocity in the riveris 0.35km/day.
The smooth surface that provides the support at C lies in the y-z plane. Determine the reaction components that the ball and socket exert on rod ABC, the tension in cable BD, and force the smooth wall exerts on end C of rod ABC.
