temperature are 625 kPa and 820 K. Assume exhaust system pressure is 103 kPa, the specific heat ratio is 1.4 and R =287J/ kg.K. The
effective area of the valve is (SI unit):

Dye for our new line of blue jeans is being blended in a mixing tank. The desired color of
blue is produced using a concentration of 1500 ppm blue dye, with a minimum acceptable
concentration of 1400 ppm. At 9 A.M. today the dye injector plugged, and the dye flow was
interrupted for 10 min, until we realized the problem and unclogged the nozzle. For how
many minutes was the flow leaving the mixer off-specification (< 1400 ppm)? How many
gallons of off-spec dye were made? See Fig. P5-15.

Problem -1
A tank is initially empty. A liquid with p = 62.4 Ibm/ft is poured into the tank at a constant mass flow
rate of mi = 7 lbm/s. The tank has cross-sectional area A = 0.2 fe, and the fluid in the tank has a
%3D
variable height H(t). There is a hole at the bottom of the tank. The fluid flows out of the tank at a rate
proportional to the fluid height: rme = kH, where k= 1.4 lbm/ft/s. Find H(t). A sketch is given in Fig. P.1.

Flocculation is to be designed with two trains and five compartments per train. The total detention time in this process is to be 25 minutes, and the average temperature of the water flowing into the plant is 10°C. The velocity gradient in the first compartment is to be 70 s¹. Make the following design decisions for the first compartment: a) Determine the dimensions of the compartment. b) Determine the diameter of the impeller. c) Determine the water power required. d) Determine the maximum rotational speed. e) Estimate the pumping capacity of the impeller and circulation time in the tank.arrow_forwardFluid Mechanic Water flows from the ground floor to the second floor of a three-story house as shown in the figure above.

Water flows in the annulus of a hori- zontal, concentric-pipe heat exchanger and is being heated from 40°C to 50°C in the exchanger which has a length of 30 m of equivalent straight pipe. The flow rate of the water is 2.90 x 10 3m/s. The inner pipe is 1-in. schedule 40 and the outer is 2-in. schedule 40. What is the pressure drop? Use an average temper- ature of 45°C for bulk physical properties. Assume that the wall temperature is an average of 4°C higher than the average bulk temperature so that a correction can be made for the effect of heat transfer on the friction factor. ompnongibia Flow Starting witharrow_forwardIt is required to pump cooling water from storage pond to a condenser in a process plant situated 10 m above the level of the pond. 200 m of 74.2 mm i.d.pipe is available and the pump has the characteristics given below.
