Pump A has HA= -2.15E-4×GPM2+0.015 ×GPM + 250, and pump B has Hb= -2.95E-4×GPM2+0.020×GPM + 210. These two pumps are combined in parallel. What is the head produced by these pumps in parallel when the flow rate is 201 GPM?

Consider the balanced reaction of acetylsalicylic acid (HA) to produce benzoic acid (HB). HA(aq) + B^1-(aq) <=> A^1-(aq) + HB(aq) At 25°C the equilibrium constant of this reaction is 5.71. Assuming one begins with 0.3740-M of both HA and B^1- (nothing else), (a) determine the equilibrium amounts of [HA] and [HB] at 25°C. Hint: a quadratic should not be required. Retain four decimal digits in the reaction table and answer. Let us now consider a different equilibrium mixture for...

Using the flow rate of 250 gpm, select a plastic pipe diameter (2”, 4”, 6”, 8”, 10”…) & determine the approximate pump head based on the following: Minor pipe losses include 6-90 degree bends (standard) and one plug valve straightway. Document your source for your K-values. Document which calculation method you used to calculate the total pump head. To save energy, choose the largest pipe diameter that provides the recommended 2.0 fps velocity of flow. Assume nominal pipe diameters as...

The hemoglobin B gene (Hb) has a common allele (A) of SNP (rs 332) that encodes the HbA form of (adult hemoglobin) and a rare allele (T) that encodes the sickling form of hemoglobin, HbS. Among 571 members of the Yoruba tribe in Nigeria, 440 were A/A. 129 were A/T, and 2 were T/T individuals. Use the chi-square test to determine whether these observed genotypic frequencies fit the Hardy-Weinberg expectations. Please show work.
