Three kg of gas in a piston–cylinder assembly undergo a process during which the relationship between pressure and specific volume is Pv0.5=constant. The process begins with P1=250 kPa and V1=1.5 m3 and ends with P2=100 kPa. Determine the final specific volume, in m3/kg.

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.
