A total of 500 mm of rain fell on a 75 ha watershed in a 10 hour period. Compute the average rainfall intensity and the total volume of rain that fell on the watershed.
When using singularity functions, if I have a reactionary moment at a cantilever connection, do I use the right hand rule to solve the moment and determine it's direction through the reactions
Air enters an adiabatic nozzle steadily at 300 kPa, 200?C, and 30 m/s and leaves at 100 kPa and 180 m/s. The inlet area of the nozzle is 80 cm2. Determine (a) the mass flow raw through the nozzle, (b) the exit temperature of the air, and (c) the e..
How do you calculate pH of water at 25 degrees that contains 0.6580mg/l carbonic acid. Assume that [H+] =[HCO3-]at equilibriumand ignore the dissociation of water.
A ten-foot high wall will retain a medium dense sand backfill. Determine the Rankine earth pressure diagram and the total active force on the wall.
Write Darcy's equation in 2-D. There are three piezometers in an unconfined sand aquifer as shown below. The head measurements at A = 104.56 ft, B = 104.53 ft, C = 103.42 ft. The rate of recharge here is estimated to be 1.25 ft/yr.
A simple steam power plant operates at steady state with water circulating through the components with a mass flow rate of 100 kg/s. Stray heat transfer, kinetic energy and potential energy effects are negligible.
The volume of the system is doubled from 1 m^3 to 2 m^3 while 200 kJ of heat is added to the system. If no work is done except for the boundary displacement work and the pressure remains constant at 101.3 kPa (1 atm) throughout the process,
what was involved in the first far-reaching, comprehensive study of Earth's oceans?
Refrigerant 134a enters the compressor of a vapor compression heat pump at 15 psi and 0 °F and is compressed to 160 psi and 160 °F. Liquid enters the expansion valve at 160 psi and 95 °F. At the valve exit the pressure is 15 psi.
A car is traveling along a road at a uniform velocity when at time zero the driver recognizes a hazard. At a moment 0.8 seconds later the driver brakes her vehicle , resulting in her vehicle sliding 90 ft in the same direction
A pressure cooker maintains a constant pressure while food cooks in a water-steam mixture. If the pressure is higher than atmospheric, the water in the cooker boils at a higher temperature and makes cooking faster.
The phone lines to an airline reservation system are occupied 40% of the time. assume that the events that the lines are occupied on successive calls are independent. assume that 20 calls are placed to the airline.
