A venturi is constructed of a 10.0 cm pipe with a 2.0 cm diameter throat. Water pressure in the pipe is twice atmospheric pressu
postnew [5]

Answer:

P_t=5066250.0696\ Pa=50\ atm

Explanation:

Given:

  • diameter of pipe, d=0.1\ m
  • diameter of throat, d_t=0.02\ m
  • velocity of flow, v=0.4\ m.s^{-1}

<u>Pressure in the pipe is twice the atmospheric pressure:</u>

P=2\times 101325=202650\ Pa

<u>Now the force of flow of water:</u>

F=P\times A

<u>now we find cross sectional area of the pipe:</u>

A=\frac{\pi.d^2}{4}

A=\pi \times\frac{0.1}{4}

A=0.007854\ m^2

<u>Therefore,</u>

F=202650\times 0.007854

F=1591.6094\ N

<u>Now the area at throat:</u>

A_t=\frac{\pi.d_t^2}{4}

A_t=\frac{\pi\times 0.02^2}{4}

A_t=0.000314\ m^2

<u>Therefore pressure at throat:</u>

P_t=\frac{F}{A_t}

P_t=\frac{1591.6094}{0.000314}

P_t=5066250.0696\ Pa=50\ atm
