The horizontal lawn sprinkler has a water flow rate of 4.0 gal/min introduced vertically through the center. The density of water is 1.94 slug/ft?Estimate the retarding torque (in Ibröft) required to keep the a from rotating. d= 4 in R = 6 in
For the table below, design an ion exchange system for the removal of calcium. The flow rate to be treated is 5.45 ML/d. The system should be sized so that the minimum time between regenerations is 72 h. The column diameter should be 3 m and there should be at least 2 columns. Pilot testing indicates optimal regeneration efficiency corresponded to using 10% NaCl solution (specific gravity = 1.07) at a salt usage rate of 310 kg NaCl per m3...
A cross-flow heat exchanger used in a cardiopulmonary bypass procedure cools blood flowing at 4 L/min from a body temperature of 37°C to 25°C in order to induce body hypothermia, which reduces metabolic and oxygen requirements. The coolant is ice water at 0°C, and its flow rate is adjusted to provide an outlet temperature of 13°C. The heat exchanger operates with the blood flow unmixed and the water flow mixed, and the overall heat transfer coefficient is 750 W/m2.K. The...
please solve The rate at which water is flowing into the boat is given in the table below. Estimate the volume of the water that has flowed into the boat during 20 minutes using right hand sums, left hand sums, the midpoint rule, the trapezoid rule. Which one is an upper estimate? Which one in a lower estimate? Why? 0 5 10 15 20 rO liters/minute 20 25 27 16 3 t minutes The rate at which water is flowing...
Hydrodynamic losses in pipe flow are characterized by measuring the pressure drop over a length of pipe L. If you anticipate using flow rates of 1.0 gals/min through 3/8" i.d. smooth-wall tubing, and want a pressure drop of 12 kPa, what length, L, of tubing should you use? Express your answer in meters. Note: You will note that this problem statement uses mixed units, which unfortunately are a fact of life in engineering calculations. You should know how to do...
Problem #5 The figure below shows a submersible pump being used to circulate 60L/min of water based coolant (sg=0.95) to the cutter of a milling machine. The outlet is through a 3/4" Sch 40 steel pipe. Assuming a total energy loss due to the piping is 3.0 N.m/N, calculate the total head developed by the pump and the power delivered to the coolant. Milling machine Flow . C Problem 14 The pipeling shown takes water from a reservoir and terminates...
1. Consider the following figure below that shows two brine tanks r gal/min fresh water Tank 1 anks 2 containing V and V gallons of brine respectively. Fresh water flows into tank 1, while mixed brine flows from tank 1 into tank 2. Let x,() denote the amount (in pounds) of salt in tank i at time for i-1,2. If each flow rate is r gallons per minute, then a simple account of salt concentration yields the first-order system where...
a) The following figure shows a water dam built for a hydroelectric power project running constantly round the year. During a dry season, it acts as water reservoir of constant height 80 m. Meanwhile rainy season, water flow of 3 m/s is added to the system. (Water density 10x10 kg/m' and volume flow, V = 45x10 m/s respectively and the gravitational acceleration is about 9.8 kg/m for both seasons). Evaluate the followings: Ravet afsec RE Figure 2: Water flow utilization...
