A hot water heating system has developed length of 200 feet of 1-inch type M tubing....
h A hot water heating system pumps water through a fired heater (furnace) then to a convector to transfer the heat to the room air. (In a real system there would be many convectors in parallel / series, but we have simplified the system to make the details easier to manage.) The piping is 2 inch schedule 40 commercial steel (roughness 0.05 mm) with a total length of 100 m The furnace and the convector can be represented by minor...
A system using 10-inch (10") internal diameter pipe requires a selection of flanged valves. Consider 10" ball valves, gate valves, globe valves, and check valves in the fully-open position; and butterfly valves in a variety of open positions. FNW has been chosen as the equipment supplier; the relevant data sheets can be found on Desire2Learn (see below for information on valve part numbers and cor- responding files). The data sheets give valve coefficients (C,): flow rates in GPM corresponding to...
1. Water is pumped from a low reservoir to a high reservoir that is 20 m higher in elevation. The water is flowing at 1.5 m/s through a 305 mm internal diameter piping system. The water is at 18 degrees C. There are 1,000 m of piping, six standard 45 degree bends, two standard 90 degree bends, a branch flow tee, three gate valves, a swing check valve, a square inlet and a square outlet. The piping and valves are...
The total length of the piping system made of cast iron providing hot water to a house is considered to have a 42m length with a constant diameter. The entrance gage pressure is 85 kPa and exit at 15 kPa gaged. Consider the water density equal 980 Kg/m' and the viscosity 1.138x10 Kg/ms. a) Compute the piping system diameter if the volumetric flow rate provided by this system is equal to 0.1 L/s. There is no pump present in this...
A pump transports water from Tank 1 to Tank 2 through a constant-diameter piping system as shown below (not to scale). The flow rate is controlled by two gate valves, the gate valve I controls the main pipeline, while the gate valve II controls the loop line from T-joint A to T-joint B. All pipes are galvanized steel pipe of diameter D = 4 in. It has a total length of Li2= 620 ft from tank 1 to tank 2....
The figure below shows a condenser/cooling tower pipe system needed to remove heat from a water cooled refrigeration condenser and reject the heat to the atmosphere. The amount of heat to be rejected to the atmosphere is 480,000 Btu/hr. The water enters the condenser at 85"F, and the temperature rise of the water through the condenser is 10°F. The total length of the piping in the system is 60 ft. Fittings are as shown. Assume bends to be as shown...
A secondary hot-water service system has 55m of 28mm circulation pipework and 40m of 15mm circulation pipework. Water leaves the cylinder at 65°C and returns at 60°C. Air temperature around the pipes is 15°C. Pressure loss rate in the pipework is 260N/m'. The frictional resistance of the pipe fittings is equivalent to 25% of measured pipe length. Specify the head and flowrate required for the secondary circulation pump and choose a suitable pump. Use Table 4.3 and Fig. 4.16. Table...
1/9 1 Piping system (14 points) Water is pumped from a reservoir to a large receiver vessel which is maintained at p4 6 bar (absolute) through the operation of the pump and a high pressure nitrogen supply that bleeds into the tank through a regulator. The water enters through an opening at the top of the vessel. A drain is provided at the low point in the system. Elevations are as shown. All valves are gate valves (k = 0.15)...
