Aplate and frame filter press with 12 frames is used to filter slurry at constant pressure. total filtration area is 65 ft2 and the filter delivers 360 lb of filtrate in 40 mins. if 8 more frames are added to the filter, the other conditions remaining the same, how long would it take to produce 360lb of filtrate? assume that the initial resistance is negligible.
a. 14.40 min
b. 7.5 min
c. 21.72 min
d. 49.17 min

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]
