QUESTION 3Water must flow over a distance of 2 800 m from a large catchment dam to a turbine. [1The water level in the catchment dam is 1 620 m above sea level and the turbine issituated 1 275 m above sea level. The efficiency of transmission is 65% and 300 kWmust be transmitted from the pipeline to the turbine. If f 0.007, determine the numberof 200 mm diameter pipelines, which must be laid in parallel, needed to transmit therequired power.F9F10F6F7F8F424&4.6.785

Hot oil is pumped through a heat exchanger (see figure below) at a flow rate of 0.5 L/s. An inlet manifold equally distributes the oil into 20 parallel, 5-mm-diameter copper tubes that are about 1 m in length. The oil cools down as it flows through the copper tubes. Oil then exits through an outlet manifold. The viscosity of the oil is 250 centipoise and its density is 950 kg/(m^3). Assuming uniform pressure in the manifolds and laminar flow through the tubes. calculate the total head loss (in meters) across those 20 copper tubes. COPPER TUBES MANIFOLDS Round your answer to 2 decimal places.

Water is pumped through a 750ft long inch nominal diameter sch 40 pipe. The difference in height between the outlet and inlet planes is given as 50 ft. Pump efficiency is 80% and the power of the motor is 20 horsepower. Friction losses are given as 50 ft-lbt / lbm. Calculate the flow rate in the pipeline.
As shown in the figure, the water flows from the ground floor of a three-storey house to the second floor through pipes of 20 mm diameter (average roughness of the pipe material = 0.0015 mm) at a volumetric flow rate of 0.75 L / s. Water is discharged from the system to atmospheric pressure through a tap with a 12 mm diameter outlet. There are 4 winged elbows, one ball valve and one faucet throughout the installation. Calculate the effective pressure at point 1. (psu=998 kg/m3, usu=1.12x10-3 Pa s, g=9.81 m/s2)
Which of the following equations below describes the system head of the piping shown below. The total length of the pipe is 154 ft. Take the friction factor to be 0.026.
