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:
Explanation:
speed of motor (N)=1500 rpm
power=4 hp = =2.9828 KW
service factor(k)= 2.75
now,
torque rating
Parallel Resistor Equation
If the two resistances or impedances in parallel are equal and of the same value, then the total or equivalent resistance, RT is equal to half the value of one resistor. That is equal to R/2 and for three equal resistors in parallel, R/3, etc.
