Answer 81 - (a)(i) Best pipe size needed = 0.75 inches for the capacity of 75 cubic feet per hour. Data for a metallic pipe of 60 feet in length and maximum capacity of 138 cubic feet per hour instead of 66 cubic feet per hour are selected. (ii) Range is more than 138 but less than or equal to 260 cubic feet per hour for pipe size of 1 inch. (b) Best pipe size needed = 0.75 inches for the capacity of 75 cubic feet per hour. Data for a metallic pipe of 60 feet in length instead of 50 feet and maximum capacity of 138 cubic feet per hour instead of 66 cubic feet per hour are selected.

GENETIC ENGINEERING - EXAMPLE 27.3 : (a) Male with genotype GGmm and phenotype gray wingless mates with female with genotype ggMM and phenotype black winged in fruit flies. G is dominant to g in color. M is dominant to m in wing shape. If the actual distribution of the second generation of the fruit flies was as follow : 890 gray wingless, 900 black winged, 115 gray winged, 95 black wingless, calculate the recombination frequency between the two genes and distance in recombination units. Let 1 map unit = 1 % recombination. (b) A DNA molecule has 180 base pairs and 20 % adenine. How many cytosine nucleotides are present in this molecule of DNA?

CHEMICAL FLUID MECHANIC - EXAMPLE 3.1 : Water flows through a pipe with circular cross sectional area at the rate of V / t = 80 L / s where V is the volume and t is time. Let Av = 80 L / s where A is cross sectional area and v is velocity of fluid. For point 1, the radius of the pipe is 16 cm. For point 2, the radius of the pipe is 8 cm. Find (a) the velocity at point 1; (b) the velocity at point 2; (c) the pressure at point 2 by using Bernoulli's equation where P + Rgy + 0.5 RV = constant. P is the pressure, R = density of fluid, V = square of fluid's velocity, g = gravitational constant of 9.81 N / kg and y = 2 m = difference of height at 2 points. The pressure of point 1 is 180 kPa.
