<em>Logs.</em>
<em>Like data logs. Sometimes people make these logs to keep tabs on other people or to get important information put down somewhere that way it is saved and can be looked back upon later. Anytime someone makes an action on the computer, it makes a TMP file representing a log of what you want it to do before the computer quickly get's rid of the file.</em>

Answer:
number of stages for the pump is 4
Explanation:
given data
water head Hm = 50 m
flow rate r = 0.1 m³/s
rotating N = 1800 rpm
to find out
optimal number of stages for the pump.
solution
we consider here specific speed does not exceed more than 82
so Ns formula will be
Ns =
here Ns id 82 and N is rotating and r is flow rate
so
82 =
so H = 13.23 m
so
number of stage n is
nH = Hm
n =
n = 3.77 ≈ 4
so number of stages for the pump is 4
Your answer is correct the last procedure of a vehicle starting is selecting the appropriate gear for the right situation. (D)
Answer
given,
oil barrel weight = 1.5 k N = 1500 N
weight of the barrel = 110 N
Assuming volume of barrel = 0.159 m³
weight of oil = 1500-110
= 1390 N
= 8742.14 N/m³
= 141.84 kg
= 892.05 kg/m³
= 0.892
