Answer:
Given that
Mass flow rate ,m=2.3 kg/s
T₁=450 K
P₁=350 KPa
C₁=3 m/s
T₂=300 K
C₂=460 m/s
Cp=1.011 KJ/kg.k
For ideal gas
P V = m R T
P = ρ RT


ρ₁=2.71 kg/m³
mass flow rate
m= ρ₁A₁C₁
2.3 = 2.71 x A₁ x 3
A₁=0.28 m²
Now from first law for open system

For ideal gas
Δh = CpΔT
by putting the values


Q= - 45.49 KJ/kg
Q =- m x 45.49 KW
Q= - 104.67 KW
Negative sign indicates that heat transfer from air to surrounding
Answer:
Both come from the sun
Both are reusable sources
and both don't cause pollution
Explanation:
Answer: Projectile
Explanation:
A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity.
Answer:
The correct answer is "20.8 kN" and "31 kN". A further explanation is given below.
Explanation:
- The angular touch bearing seems to be a fine replacement while accommodating radial and even some displacement pressures.
- You may receive static as well as dynamic scores from either the manufacturer's collections.
The load ratings should be for the SKF bearing including its predetermined distance:
Static load
= 20.8 kN
Dynamic load
= 31 kN
