Determine the rainfall excesses during successive 30-min. period by the NRCS method using storm pattern given in the table 1. The watershed is part of an urban impervious area. The hydrologic soil group is C and the soil is in a dry condition (condition 1). Time(min) 30 60 90 120 150 180
Rainfall(in/hr) 0.5 0 0 4.5 5 3

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
