Answer:
hello your question has some missing information attached below is the missing information
answer :
a) 9.17431 kg/s
b) 2598.4374 kW
Step-by-step explanation:
a) Calculate mass flow rate at inlet 1
Given data :
AV1 = 0.01 m^3/s
pressure ( P1 ) = 5 bar , temp ( T1 ) = 150°C
therefore : m1 = AV1 / v1 ------ ( 1 )
where : v1 = 0.00109 m^3/kg ( value gotten from compressed table )
back to equation 1
m1 = ( 0.01 m^3/s / 0.00109 m^3/kg ) = 9.17431 kg/s
b) Calculate the rate of heat transfer
first determine mass balance
m3 = m1 + m2
= 9.17431 + 19 = 28.17431 kg/s
apply the energy balance equation to determine the rate of heat transfer
m1*h1 + m2*h2 = m3*h3 + Q
∴ Q = m1*h1 + m2*h2 - m3*h3 ------------ ( 1 )
where :
h1 = 632.266 kJ/kg value gotten from compressed water table
h2 = 2812.45 kJ/kg value gotten from superheated steam table
h3 = 2010.2965 kJ/kg value gotten from saturated pressure table
input values into equation 1 above
Q = 2598.4374 kW . the energy moves from the chamber to the surroundings
