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:
The answer to the range of a cooling tower is the difference between the temperature of the water going in and the temperature of the water going out of the tower.
Explanation:
Cooling towers are used to cool a stream of water using the air of the environment where it's placed or installed. In theory, the lowest temperature the water can be cooled to would be the wet bulb temperature (temperature of the air going in the cooling tower). The range would be the difference (R=Ti-To) between the temperature of the hot water going in and the cooler water going out.
Answer:
1.52 kw
Explanation:
A1 = 0.45
A1 = 0.25
Flow rate = 1.5m³/sec
P1 = 105
P2 = 106
P-air = 1.225kg/m³
I applied bernoulli's equation as I continued (check the attachment)
hp = 83.21371+1.3686 = 84.4823
Pf = p-air x g x Q x hp
Pf = 1.225x9.81x1.5x84.4823
Pf = 1522.868W
When converted to KW we get
Pf = 1.52 KW
Thank you!
