In all liquid refrigerant lines, the pressure at the bottom of a vertical rise isgreater than the pressure at the top of the rise. For R-134a, the pressure isabout 0.5144 lb/sq in or less for every vertical foot of pipe that is used. Thevertical rise between this condenser and evaporator is 7.5 feet. How muchless is the pressure at the top of the rise than at the bottom?

Note:Use-the relevant-chart-for-each-preblem------ 5. For a vapour compression refrigeration system using R-22 as refrigerant, condenser outlet temperature is 40°C and the evaporator inlet temperature is -20'C. In order to avoid flashing of the refrigerant, a liquid-suction vapour heat exchanger is provided where liquid is subcooled to 26°C. The refrigerant leaves the evaporator as saturated vapour. The compression process is isentropic. Find the power requirement and coefficient of 1 performance if capacity of the system is 10 kW at -20 °C. Show the cycle on temperature- entropy and pressure-enthalpy diagrams. The specific heat of vapour refrigerant is 1.03 kJ/kg K. (Same as Example 14) Please solve the question on a piece of paper and using tables with illustrations

A chiller tank with a water volume capacity of 20 M3. There are 2 chiller units with a capacity of 20 PK each to cool the water in the chiller tub. 1 unit of cold chiller water transfer pump is used to the production area with a capacity of 5 M3/hour. The chiller water temperature sent to production is 15 oC and the pressure is 4 bar. The distance of the 2 inch stainless pipe from the chiller pump to the double jacket mixing tank production is 100 meters. The diameter of the inlet and outlet pipes for the double jacket mixing tank is 1 inch. The chiller water storage capacity in a conventional double jacket mixing tank is 400 liters. (mixing tank capacity is 1500 kg). Questions: 1. How much time is needed to cool the water in the mixing tank from the initial temperature of 90 oC to 40 oC? 2.
