Whal will be the HRC fuse rating of a 3phase
415V,50Hz,0.85pf,95%efficiency,30KW,1450rpm induction
motor,starting with a DOL starter.and describe the Fuse
rating calculation.
Answer / vishu
Calculate the rated current of the motor it will be 50A.
let us assume The permissible overload is 20%
then fuse rating will be 50*1.2= 60A

GENETIC ENGINEERING - EXAMPLE 27.2 : (a) Three genes, I, J and K are available. All these genes are linked with respect to one another. If the percent recombination between I and J is 8 %, that between J and K is 10 %, and that between K and I is 18 %, what is the order of the gene? (b) Twenty six genes, a, b, c, d, e, f, ... x, y and z are available. All these genes are linked with respect to one another. If the percent recombination between a and b is 3 %, between b and c is 3 %, between c and d is 3 %, ... between w and x is 3 %, between x and y is 3 %, between y and z is 3 %, then what is the percentage recombination between b and y?
