Answer:
it would be rotation I think
We are given with conditions on temperature, pressure and volume of gas. In this problem, we apply ideal gas law PV = nRT to solve what are asked.
1. PV = nRT ; n = m/MM
16.5 x10^6 Pa * 0.003785 m3= n * 8.314 Pa m^3/ mol K * (23+273) K
n = 25.38 mol; mass = 812.08 grams.
2. V at STP is 22.4 L/mol
3. PV = nRT = 1.5 atm * 0.003785 *1000 L = <span>25.38 mol * 0.0821 L atm/mol K * T ; T = 2.72 K
4. P * 55 m3/1000 = 25.38 mol * </span><span>8.314 Pa m^3/ mol K</span><span> * (24+273) K
P = 1139. 45 kPa</span>
Answer:
42.4m/s
Explanation:
To develop the problem it is necessary to apply the concepts related to thermodynamic work and Bernoulli's principle in which the behavior is described of a liquid moving along a stream.
The work of an incomprehensible liquid is given by the equation,
Where,
= Mass flow
= Specific Volumen
P = Pressure
Our values are given by,
= 2kW
Table 1 for saturated water in 10°C
We need to find the mass flow, then re-arrange for
To find the Spray velocity, we apply Bernoulli equation, because at the Nozzle there is not Work or Heat transfer related. Then,
Therefore the spray velocity is 42.4m/s
Add 150 plus 120 and what you get is your answer
