A hydronic system consists of two coils, two orifices and a chiller as shown below. he pipe is commercial steel and all the elbows and Tee's are standard threaded type. Determine the size of the pipes, if the maximum speed of water is not to exceed 4 ft/s. The flow rate through the chiller is 120 gpm, while that through the coil A is 80 gpm. The head loss (ft) in chiller, coil A, coil B and orifices can be...

) 25 points - Water flows in a piping system a section of which is shown below.Pipe is 30 mm ID commercial steel pipe. Velocity of flow is 1.6 m/s and is constant throughout. Pressure at Pt is 200 kPa. All the valves are fully open gate valves, all the elbows are regular 90° threaded. For water, p:1000 kg/m3, 0.00108 N-s/m2. Other necessary data is given on the diagram. Assume the flow is incompressible and steady. Determine the volume flow...

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 two-pipe direct return chilled water system with an expansion tank is used to circulate water for cooling three identical loads in a commercial building. Each load is connected with a balancing valve, zone valve and thermostat. Given that the cooling capacity of each load is 50 kW, density of water 1000kg/m3, a specific heat of water Cpw 4.185 kJ/kg K and gravitational constant 10 m/s2. (a) Sketch a schematic of the system illustrating all the components. (6%) Legend Expansion...

Water (density 998 kg/mº, dynamic viscosity 0.001 Pa s) is pumped between two reservoirs at a volumetric flow rate of 0.006 m/s through a 120-m long pipe of 5 cm diameter. The roughness ratio of the pipe is a/d = 0.001. There are some fittings and valves in the pipe system, as shown in Figure Q1. The loss coefficients of the valves and fittings can be found in Table Q1. The Darcy friction factor can be found in the Moody...

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)...
