Answer:
diameter is 14 mm
Explanation:
given data 
power = 15 kW
rotation N = 1750 rpm
factor of safety = 3
to find out
minimum diameter
solution
we will apply here power formula to find T that is
power = 2π×N×T / 60    .................1
put here value
15 × = 2π×1750×T / 60
 = 2π×1750×T / 60
so 
T = 81.84 Nm
and 
torsion = T / Z                        ..........2
here Z is section modulus i.e = πd³/ 16 
so from equation 2 
torsion = 81.84 / πd³/ 16
so torsion = 416.75 / / d³     .................3
so from shear stress theory 
torsion = σy / factor of safety
so here σy = 530 for 1020 steel
so
torsion = σy / factor of safety
416.75 / d³ = 530 ×  / 3
 / 3
so d = 0.0133 m
so diameter is 14 mm

Answer:
 
Explanation:
Given that
L= 50 m
Pressure drop = 130 KPa
For Copper tube is 3/4 standard type K drawn tube
Outside diameter=22.22 mm
Inside diameter=18.92 mm
Dynamic viscosity for kerosene

Pressure difference given as

Where
L is length of tube
μ is dynamic viscosity
 Q is volume flow rate
 d is inner diameter of tube
ΔP is pressure drop
Now by putting the values



So flow rate is 
 
        
             
        
        
        
It is motor oil, as oil is used to reduce friction
