When a liquid flows in a horizontal pipe, the force component in horizontal direction is 650 N.
<h3>What is force?</h3>
The force which acts on the liquid depends upon the density of fluid, it volume and acceleration due to gravity.
Given, mass flow rate m = 45 kg/s, D1 =D2 =10cm, density ρ =1000 kg/m³ and momentum flux correction factor is K =1.03.
Using the Bernoulli's theorem, we have
P1/ρg +V1²/2g +z1 =P2/ρg +V2²/2g +z2
P1/ ρg =z2 - z1 = 0.5 m
P1 = 4.905kPa
The force in horizontal direction is
Fx = P1A1 +ρQ(V1 - V2cosθ) x K
here θ =180°
ρAV1 =m =45
1000 x π/4x (0.1)² x V1 =45
V1 = 5.732 m/s
Fx =(4.905 x π/4 x 0.1²) x 10³ + 42 x 5.732 x 2
Fx = 650N
Thus, the force component in horizontal direction is 650N.

Answer:
NOT WISE
Explanation:
given,
T₁ = 87⁰C = 273 + 87 = 360 K
T₂ = 27⁰C = 273 + 27 = 300 K
work output given = 10 J
efficiency will be equal to :
output delivery = η ₓ input
= 0.166 ₓ 40
= 6.66 J
hence, the output of new engine is less than the old one so, investing in new engine will not be feasible.
Answer:
Explanation:
The turbine at steady-state is modelled after the First Law of Thermodynamics:
The specific enthalpies at inlet and outlet are, respectively:
Inlet (Superheated Steam)
Outlet (Liquid-Vapor Mixture)
The power produced by the turbine is:
Idk what that means i’m sorry
Answer:
ABS warning light – it is turned on every time there's something wrong with the Anti-lock Brake System. Note that the ABS symbol is activated once the drive starts the engine but it's automatically turned off after a few seconds.
