A pump must be able to deliver 34 L/s of crude castor oil at 25°C ρ = 0.934 g/mL and μ = 0.078 Pa.s. It is known that, due to th
Reptile [31]

Castor oil is increasingly becoming an important bio-based raw material for industrial applications. The oil is non-edible and can be extracted from castor seeds from the castor plant belonging to the family Euphorbiaceae. The oil is a mixture of saturated and unsaturated fatty acid esters linked to a glycerol. The presence of hydroxyl group, a double bond, carboxylic group and a long chain hydrocarbon in ricinoleic acid (a major component of the oil), offer several possibilities of transforming it into variety of materials. The oil is thus a potential alternative to petroleum-based starting chemicals for the production of materials with variety of properties. Despite this huge potential, very little has recently been reviewed on the use of castor oil as a bio-resource in the production of functional materials. This review therefore highlights the potential of castor oil in the production of these diverse materials with their projected global market potential. The review gives the background information of castor oil and its geographical availability, the properties and its uses as bio-based resource for synthesis of various materials. The review further highlights on the use of castor oil or ricinoleic acid as a green capping agent in the synthesis of nanomaterials.

A 25 kVA transformer has an iron loss of 200 W and a full-load copper loss of 350 W. Calculate the transformer efficiency for th
Oksanka [162]

Answer:

a. 97.32 percent

b. 97.92 percent

c. 95.91 percent

Explanation:

given parameters

apparent power, S = 25 kVA

Iron Loss, Piron = 200 W

copper Loss at full load, P cufl = 350 W

let the transformer efficiency at full load be E

let the real power be P out

a.

at full load and 0.8 power factor

P out = Scos∅

        = 25 x 10³ x 0.8

        =20000 W or 20 kW

efficiency at full load is

E =  (P out)/(P out + P iron + P cufl) x 100%

   =  (20000)/(20000 + 200 + 350) x 100%

   = 97.32%

b.

at 70% of full load at unity power factor of 1

Pout = 70% x Scos∅

        = 0.7 x 25 x 10³ x 1

        =  17,500W or 17.5kW

copper loss at 70% full load

P cu0.7fl = (70%)² x 350

                 = (0.7)² x 350

                 = 171.5 W

Iron loss remain the same, P iron = 200 W

Efficiency of transformer at 70% of full load

E =  (P out0.7)/(P out0.7 + P iron + P cufl0.7) x 100%

  =  (17500)/(17500 + 200 + 171.5) x 100%

  = 97.92%

c.

at 40% of full load at a power factor of 0.6

P out = 40% x Scos∅

= 0.4 x 25 x 10³ x 0.6

        =  6000 W or 6 kW

copper loss at 40% full load

P cu0.7fl = (40%)² x 350

                 = (0.4)² x 350

                 = 56 W

Iron loss remain the same, P iron = 200 W

Efficiency of transformer at 40% of full load

E =  (P out0.4)/(P out0.4 + P iron + P cu0.4) x 100%

  =  (6000)/(6000 + 200 + 350) x 100%

  = 95.91%
