Exercise 2: According to an appliance manufacturer, the 4-in.-diameter vent on a clothes dryer is not to contain more than 20 ft of pipe and four 90° elbows. Under these conditions determine the air volumetric flow rate if the gage pressure within the dryer is 0.20 inches of water. Assume both the specific weight and the kinematic viscosity of the heated air to be constant and equal to y=0.0709 bf/ft?, and v=µp=1.79x10 -4 ft2/s, respectively, and that the roughness of the vent pipe surface is equivalent to that of galvanized iron.

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?
