Avapour compression system has a capacity of 50 kw of refngeration when operating on r22, a condensing temperature of 35°c and an evaporating temperature of-10°c calculate 4.1 the refrigeration effect in kj/kg. 4.2 the crculation of the refrigerant in kg/s 4.3 the power required by the compressor in kw, 4.4 the coefficient of performance, 4.5 the volume flow rate measured at the compressor suction, 4.6 the power per kw refngeration, 4.7 the compressor discharge temperature, and 4.8 the compressor efficiency of the actual discharge temperature is 62 c

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

i will answer your question if you answer mine

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
