Answer:
power developed by the turbine = 6927.415 kW
Explanation:
given data
pressure = 4 MPa
specific enthalpy h1 = 3015.4 kJ/kg
velocity v1 = 10 m/s
pressure = 0.07 MPa
specific enthalpy h2 = 2431.7 kJ/kg
velocity v2 = 90 m/s
mass flow rate = 11.95 kg/s
solution
we apply here thermodynamic equation that
energy equation that is
put here value with
turbine is insulated so q = 0
so here
solve we get
w = 579700 J/kg = 579.7 kJ/kg
and
W = mass flow rate × w
W = 11.95 × 579.7
W = 6927.415 kW
power developed by the turbine = 6927.415 kW

Answer:
During installation, the air transformer should be located at least 25 feet minimum from the compressor unit
Explanation:
An air transformer is used to remove the dirt, water and oil in the compressed air and to filter as well as to provide air regulation and are required in spray finishing tasks that calls for a regulated clean and dry supply of air
The air transformer measures the pressure of the regulated air and can also come with air outlets for air operated tools, blow guns, spray guns, as well as for other purposes
In order to operate efficiently, the air transformer are required to be installed at a minimum distance of 25 feet (7.6 m) from the compressor unit.
A hydraulic jump is formed between a sluice gate (upstream) and a weir (downstream) explain, with an appropriate plot, what happens if the gate opening is reduced.
"(Begin by drawing generic E-y and M-y curves beside each other).
Because this is a hydraulic jump situation, we know that the flow regime of the water through the sluice gate is super-critical. Before the opening is reduced, we have E1 (as shown on the diagram) occurring after the sluice gate, corresponding to the momentum of M1, which is conserved through the jump. The change in depths before and after the jump can be determined by finding y values at M1 from the momentum curve.
When the gate opening is reduced, the depth of flow out of the opening is also reduced. Referring back to our Energy curve, we now have E2 occurring at a shallower depth and thus a greater specific energy than E1. The corresponding momentum M2 is also greater than M1. The y values that occur at M2 can now be used to determine the new change in depths before and after the jump. As you can see, decreasing the gate opening will cause the overall change in depth through the jump will to be greater, meaning that more energy will be lost. "
