Tank truck nozzles

During normal operation the vessel would receive acid via an in-plant pipeline. It was also equipped to receive acid via tank trucks (see Figure 2-6). One of the top nozzles was... 

Application equipment 1,000 gallon tank and Meyer centrifugal pump and spray equipment was mounted on a truck bed. The tank contained 800 gals, total volume water plus insecticide and fertilizer. A ChemLawn spray gun with 40 psi at the nozzle applied 4 gallons of insecticide and water per minute per 1,000 sq.ft. 

On one facility, e.g., a certain process used both sodium hydroxide solution and sulfuric acid. As is well known, the inadvertent mixing of these two substances can create a violent and dangerous chemical reaction. The chemicals were stored in tanks as shown in Figure 6.3. The tanks were filled by trucks that used hoses connected to fill nozzles. (There were many other pipes in the area, so the situation was actually considerably more complex than what is shown in the sketch.)... 

Example 10-6 A fire truck (see Figure 10-8) pumps water to the third fioor (25 ft from ground level) of a building. Water for the pump is in an open tank on the ground. The flow rate at the nozzle must be 50 gal./min. The nozzle has a 2 in. diameter opening. The pressure loss due to friction in the hose between the pump and the nozzle is equivalent to 3 ft of water. What pressure must the pump produce Assume that a gallon of water occupies 0.1337 ft. ...
