the hydraulic residence time t is given by t=V/q where V is the volume in the tank and q is the volumetric flow rate. A theoretical residence time can be given by the relationship between concentration and time ln(C)=-(t/tav) where tav in this equation is the residence time.
formula for calculating red blood cells
No there is not i hope that helps!
divide its mass by its voulme
Mass = force ( weight) / acceleration due to gravity
v=2d/t
Divide distance by time.
b jnkmk;ou n
time
Distance = speed x time
formula for calculating through-feed grinding time
There are different formulae for calculating these variables which depend on what information is available.
You divide work by time.
Velocity= Distance/ Time Unit= m/s
Formula for calculating the area of sphere is : 4 * pi * r * r
You need to know the principal amount, the rate and the time. Then a very simply formula for calculating interest is I = PRT where P is the principal amount, R is the interest rate and T is the period of time in years.
Veloicty is distance divided by time, for a object moving in a given direction. If direction is not given, then it is speed.
