Explanation:
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:
0.65 m/min
Explanation:
The volume of material to be removed is
80*8*10 = 650 cm^3
The tool has a diameter of 4 mm and a maximum axial cutting capacity of 50 mm, so its cross section normal to advance is
0.4*5 = 2 cm^2
If the groove have to be made in T = 5 minutes the advance speed would be
V/(S * T)
650/(2 * 5) = 65 cm/min = 0.65 m/min
