We can find the change in the enthalpy through the tables A5 for Saturated water, pressure table.
For 1bar=1000kPa:




Replacing,



With the specific volume we know can calculate the mass flow, that is


Then the heat required in input is,



With the same value required of 15000m^3/h, we can calculate the velocity of the water, that is given by,



Finally we can apply the steady flow energy equation, that is

Re-arrange for Q,




We can note that consider the Kinetic Energy will decrease the heat input.

Answer:
Rate of Entropy =210.14 J/K-s
Explanation:
given data:
power delivered to input = 350 hp
power delivered to output = 250 hp
temperature of surface = 180°F
rate of entropy is given as

T = 180°F = 82°C = 355 K
Rate of heat = (350 - 250) hp = 100 hp = 74600 W
Rate of Entropy
Answer:
i)ω=3600 rad/s
ii)V=7059.44 m/s
iii)F=1245.8 N
Explanation:
i)
We know that angular speed given as

We know that for one revolution
θ=2π
Given that time t= 2 hr
So
ω=θ/t
ω=2π/2 = π rad/hr
ω=3600 rad/s
ii)
Average speed V

Where M is the mass of earth.
R is the distance
G is the constant.
Now by putting the values


V=7059.44 m/s
iii)
We know that centripetal fore given as

Here given that m= 200 kg
R= 8000 km
so now by putting the values


F=1245.8 N
