Answer:
mechanical efficiency = 54%
Explanation:
given data
power We = 44 kW
density = 860 kg/m³
rate of flow = 0.07 m³/s
inlet diameter d1 = 8 cm
outlet diameter d2 = 12 cm
pressure = 500 kPa
efficiency η = 90%
to find out
mechanical efficiency
solution
we get here shaft power is here
shaft power = efficiency × electric power
shaft power = 0.9 × 44 = 39.6
and
now we get DEmech that is
DE(mech)= m g h + (v² - u ²) .....................1
that is we can write as
DEmech = ρVgh +
= VDP + ×
Plugging in values we now have DEmech that is
DEmech = (0.07m^3/s × 500kPa) +
solve we get
DEmech = 21342 W
DEmech = 21.3 kW
mechanical efficiency is
mechanical efficiency =
mechanical efficiency = 0.54
mechanical efficiency = 54%

Answer:
time need = 17.65 minutes
Explanation:
given data
water flows in = 22 liters/minute
water flows out = 5 liters/minute
volume of water needed for a bath = 0.30 m³ = 300 Liters
Density of water = 1000 kg/m³
solution
we get here time for need to fill bath that is express as
time need = .........................1
put here value and we will get
time need =
time need = 17.65 minutes
Answer:
Steel concrete composite beams consists of a steel beam over which a reinforced concrete slab is cast with shear connectors. In conventional composite construction, concrete slabs are simply rested over steel beams and supported by them. These two components act independently under the action of loads, because there are no connection between the concrete slabs and steel beam.
