The thrust F of a screw propeller is known to depend upon the diameter d,speed of advance \nu ,fluid density p, revolution per s

musickatia [10]

Answer:

screw thrust = ML $T^{-2}$

Explanation:

thrust of a screw propeller is given by the equation = p $V^{2}$ $D^{2}$ x $\frac{ND}{V}$ Re

where,

D is diameter

V is the fluid velocity

p is the fluid density

N is the angular speed of the screw in revolution per second

Re is the Reynolds number which is equal to puD/μ

where p is the fluid density

u is the fluid velocity, and

μ is the fluid viscosity = kg/m.s = M $L^{-1}$ $T^{-1}$

Reynolds number is dimensionless so it cancels out

The dimensions of the variables are shown below in MLT

diameter is m = L

speed is in m/s = L $T^{-1}$

fluid density is in kg/ $m^{3}$ = M $L^{-3}$

N is in rad/s = L $L^{-1}$ $T^{-1}$ =

If we substitute these dimensions in their respective places in the equation, we get

thrust = M $L^{-3}$ $(LT^{-1}) ^{2}$ $L^{2}$ $\frac{T^{-1} L}{LT^{-1} }$

= M $L^{-3}$ $L^{2}$ $T^{-2}$

screw thrust = ML $T^{-2}$

This is the dimension for a force which indicates that thrust is a type of force

Evaluate each of the following and express with an appropriate prefix: (a) (430 kg)^2 (b) (0.002 mg)^2, and (c) (230 m)^3

Mekhanik [1.2K]

Answer:

a)0.185g^2

b)4μg^2( Micrograms)

c)12.167hm^3( cubic hectometer)

Explanation:

To solve this problem, we must first use the calculator to solve each of the points, then knowing the number of zeros on the left or on the right, we choose a unit with which it is better to see the unit

(430 kg)^2=184900kg^2=0.185g^2

(0.002 mg)^2=4x10^-6mg^2=4μg( Micrograms)

(230 m)^3=12167000m^3=12.167hm^3( hectometer)
