The inlet and outlet temperatures of cooling water to a certain condenser are recorded to be 30°C and 40°C respectively. If the absolute pressure in the condenser is given to be 0.11 bar, determine efficiency.

In a condenser, the temperature of steam entering in the condenser is observed to be 30°C. The condenser vacuum is recorded to be 670 mm of Hg. If the barometer reading is 760 mm of Hg, determine the vacuum efficiency.

The following data refers to a steam condenser –
Inlet temperature of cooling water = 36°C
Absolute pressure inside the condenser = 0.12 bar
efficiency = 78%
Determine the outlet temperature of cooling water.

Dalton’s law of partial pressure states that the total pressure exerted by a mixture of gas and vapour is the sum of partial pressure of the gas and partial pressure of the vapour at the common temperature.

Given specific volume of steam as 54.25 m³/kg and volume of the container as 190 m³, calculate the mass of steam present inside the container.

In a conatainer, having a mixture of steam and air, the specific volumes of air and steam are 42 m³/kg and 55 m³/kg. Calculate the total mass of the mixture present inside the container if the mass of steam inside the container is 4.23 kg.

Determine the amount of cooling water required, if the condenser (surface condenser) deals with 15000 kg of steam per hour. The steam is dry and has a latent heat of 2432 kJ per kg. The temperature of condensate is 20°C is less than the steam temperature. Also, the rise is cooling water temperature is 10°C. Take specific heat of water at constant pressure as 4.186 kJ/kg-°C.

A jet condenser is designed to handle 12000 kg of dry and saturated steam per hour. The steam enters the condenser at 38°C (dry and saturated), and the condensate leaves the condenser at 32°C. If the inlet temperature of cooling water is 10°C, find out the mass of cooling water required in kg per hour. Take latent heat of steam as 2300 kJ/kg and specific heat at constant pressure as 4.186 kJ/kg-°C.

In a jet condenser, the difference between the temperature of steam (dry and saturated) entering the condenser and the condensate leaving the condenser is 4°C. The amount of cooling water required and the mass of steam being supplied to the condenser are 900000 kg/hr and 12000 kg/hr. Take the latent heat of water to be 2300 kJ/kg and the specific heat at constant pressure to be 4.186 kJ/kg-K. If the temperature of cooling water entering the condenser is 26°C, determine the temperature of cooling water leaving the condenser.
