Question - There is a small spill of a toxic material on a paved surface of a chemical plant. This spill has width 0.8 ft and a length of 2.5 ft. The wind is a 10 miles per hour in the direction parallel to the length of the spill. Estimate the rate of evaporation in grams per hour. There is no toxin in the air at time 0 and at infinite distance from the spill. Assume air to behave as an ideal gas.

PROBLEM 1 Medium lubricating oil (SG = 0.860) is pumped through 1000 ft of horizontal 2-in pipe at the rate of 0.0436 cfs. If the drop in pressure is 30 psi, (a) what is the velocity (ft/s) of the oil? (b) What is the head loss (ft)?
3 A tank contains 100 gal of brine in which 50 lb of salt is dissolved. Brine containing 2 lb/gal of salt runs into the tank at the rate of 3 gal/min; and the mixture, assumed to be kept uniform by stirring, runs out at the rate of 2 gal/min. Assuming that the tank is sufficiently large to avoid overflow, find the amount of salt in the tank as a function of the time t. When will the con- centration of salt in the tank reach Ib/gal? How much salt is in the tank at the end of 30 min? Work Exercise 3 with the rates of influx and efflux interchanged, and find the amount of salt in the tank after 1 h instead of at the end of 30 min. Under these circumstances, when will the 4 tank contain the maximum amount of salt, and what is this amount?

An oil of specific gravity 0.89 is flowing through a horizontal venturimeter fitted to a 242 mm diameter pipe at the rate of 108 liters/s and throat diameter is 98 mm. The entrance and throat of the venturimeter are connected in the two limbs of a U-tube mercury manometer. The difference in mercury level shows 841 mm. Calculate (i) the head difference in m of oil, (ii) the theoretical discharge in m3/s, (iii) the actual discharge in m3/s, and (iv) the coefficient of discharge of a venturimeter. If instead of a U-tube mercury manometer, the pressure gauges are inserted at the entrance and throat of venturimeter. Find (v) the pressure at the throat in N/mm2, if the entrance pressure gauge shows0.13 N/mm2.
