If i had to guess, not the most amazing smell in the world, but i wouldn't know xD
Answer:
value of the rate constant is 80 mg/L-hr
Explanation:
given data
concentration of compound Cao = 90 mg/l
Ca = 10 mg/L
time = 1 hour
solution
we use here zero order reaction rate flow
-rA = K Ca
= K
-d Ca = k dt
now we will integrate it on the both side by Cao to ca we get
solve it we get
cao - Ca = K t
put here value and we get K
90 - 10 = K 1
K = 80 mg/L-hr
so value of the rate constant is 80 mg/L-hr
Answer:
a) C_v = 1.005 KJ/kgK
b) C_v = 1005.000 J/kgC
c) C_v = 0.240 kcal/kgC
d) C_v = 0.240 Btu/lbmF
Explanation:
Given:
- constant-pressure specific heat C_v = 1.005 KJ/kgC
Find C_v in units of:
a) kJ/kg·K
b) J/g·°C
c) kcal/ kg·°C
d) Btu/lbm·°F
Solution:
a) C_v is Specific heat capacity is the quantity of heat needed to raise the temperature per unit mass. Usually, it's the heat in Joules needed to raise the temperature of 1 gram of sample 1 Kelvin or 1 degree Celsius. Hence,
C_v = 1.005 KJ/kgK
b)
C_v = 1.005 KJ/kgC * ( 1000 J / KJ)
C_v = 1005.000 J/kgC
c)
C_v = 1.005 KJ/kgC * ( 0.239006 kcal / KJ)
C_v = 0.240 kcal/kgC
d)
C_v = 1.005 KJ/kgC * ( 0.947817 Btu / KJ) * ( kg / 2.205 lbm)*(Δ1 C / Δ1.8 F)
C_v = 0.240 Btu/lbmF

Answer:
1. To bring down the pressure of the refrigerant
2. To meet up with the load to be refrigerated (the amount of heat to be evacuated)
Explanation:
1. To bring down the pressure of the refrigerant
The high pressure of the refrigerant coming from the condenser require reduction to enable vaporization in the evaporator at the proper temperature
The throttling valve as a small aperture through which the refrigerant flows that lowers the pressure of the refrigerant to a point at which the refrigerant vaporize of which the refrigerant then passes into the evaporator in a partly as liquid and vapor at a low temperature and pressure
2. To meet up with the load to be refrigerated (the amount of heat to be evacuated)
The throttling valve allows more refrigerant to flow through it when there is an increased load at a higher temperature to be refrigerated
Similarly, in a condition of reduced refrigeration load, hence, a lesser amount of heat to be evacuated, the throttling valve restricts the amount of flow of the refrigerant through it.
