2. A centrifugal pump installation has been designed to discharge 0.126 ?3/? of brine (sp.gr. = 1.2). The suction pipe is 305 mm and is at the same level as the discharge pipe which is 203 mm in diameter. At the centerline of suction flange, the vacuum is 154.2 mm Hg. The discharge pressure gauge reads 0.1379 MPa and is connected 1.22 m above the discharge flange centerline. The pump is driven by a 35 KW electric motor that will not carry overload and has an efficiency of 82%. There is no significant head loss. The design conditions have changed, and is now desired to increase the capacity of the pump by increasing the speed. The motor is so designed that its speed maybe increased but its power cannot exceed its design rating. Assuming the pump efficiency to remain constant, how much can the pump capacity be increased without overloading the motor?
A steady stream of n-butanol is needed to be fed into the reactor at 40 ̊C. However, the inlet of the reactor is located 7.5 m above the reservoir tank. As such, a highly effective centrifugal pump (70% efficiency) is used for such a purpose. It was understood that the needed volumetric flow rate into the reactor is fixed at 20 m3/h. It was also noted that the n-butanol reservoir is closed but not pressurized, while the gauge pressure at the endof the discharge line is measured at 275 kPa. Given that the density of n-butanol is 810kg/m3. If the discharge pipeline was 5 cm in diameter, calculate: (i) The velocity of n-butanol at the discharge line. (ii) The total power input from the centrifugal pump. (iii) The power delivered to the n-butanol fluid.

A cryogenic vacuum pump works by condensing vapors onto some absorbent medium. This is an efficient and clean way to pump a system in a research environment. The term cryo means cold, which indicates that these types of vacuum pumps contain a refrigerant cycle to cool the internal parts. The temperature difference between the inside and outside of a typical cryogenic pump is Δ?=315 ∘C. Derive an expression to convert this difference into Fahrenheit and express the answer.
Hello, i have an example question with an answer already given. Please help me in finding its solution so i can review and see the process and understand the concept.
