Answer:
Q= 4.6 × 10⁻³ m³/s
actual velocity will be equal to 8.39 m/s
Explanation:
density of fluid = 900 kg/m³
d₁ = 0.025 m
d₂ = 0.05 m
Δ P = -40 k N/m²
C v = 0.89
using energy equation

under ideal condition v₁² = 0
v₂² = 88.88
v₂ = 9.43 m/s
hence discharge at downstream will be
Q = Av
Q =
Q =
Q= 4.6 × 10⁻³ m³/s
we know that

hence , actual velocity will be equal to 8.39 m/s

Answer:
The pressure in the tank is 70.183 k Pa
The volume of the tank is 4.73 m³
Explanation:
Volume of the liquid phase
v(f) = m(f).v(f)
= 8 kg . 0.001036 m³/kg
= 0.008288 m³
Volume of the vapor phase
v(g) = m(g).v(g)
=2 kg . 2.3593 m³/kg
= 4.7186 m³
Volume of the tank = Volume of the liquid phase + Volume of the vapor phase
Volume of the tank
= 0.008288 m³ + 4.7186 m³ = 4.73 m³
Answer:
Hey here is the answer: Hydraulic Jack and car brake is Boyle's law and syringe, soda can, and spray can is Pascal's.
Explanation:
Be careful though because with the soda can it could be very tricky. see the soda can would be placed in Charles's law but since you only have those two options it would be better placed in Pascal's law. The reason for that is because Pascal's law is based on water and gas pressure in a contained object, While Boyle's law is gas and pressure within and working with the object. So since The soda can has liquid in it would be considered in the P law. Also the same for the spray can.
