Question

The turbine blade tip speed v for r=1m and 5 rev/sec is a) 5 m/s b) 0.25 m/s c) 0.20 m/s

Answer 1

(a) 5 m/sec

Step-by-step explanation:

we have given r=1 meter

angular velocity ω =5 revolution/sec

we have to find the velocity of turbine blade tip

the velocity of turbine blade tip is given by v =rω

where v = velocity of turbine blade tip

r = radius

ω = angular velocity

so v =5×1= 5 meter/sec

so the option (a) will be the correct option as in option (a) velocity is given as 5 meter/sec
