- . A pump is used for pumping water from lake at height of 100 m consuming power of 60 kW. Inlet pipe and exit pipe diameters are 150 mm and 180 mm respectively. The atmospheric temperature is 293 K. Determine the temperature of water at exit of pipe. Take specific heat of water as 4.18 ??/??. ?An air-cooled condenser has an h value of 30 W/m2-K based on the air-side area. The air-side heat transfer area is 190 m2 with air entering at 27°C and leaving at 40°C. If the condensing temperature is constant at 49°C, what is the air mass flow rate in kg/s?

- You are designing an electric air heater for large conference rooms. A 75mm OD, 4mm wall thickness intake pipe sucks air into the unit at 2 m/s. The air passes over a 3m long heater coil and is exhausted at a temperature of 38degC. What is the average heat rate of the heater coil into the air?Hello! I'd like help with the following exercise, from Levenspiel's "Engineering Flow and Heat Exchange". Leftover air at 20ºC and 100kPa is driven by a fan through a horizontal galvanized conduit of 1 m in diameter and 10m in length at a speed of 10 m/s. What size motor should be used if its efficiency is 90% and that of the fan is 20%? I'm not sure where to start. My professor hasn't explained much about this subject.What refrigeration capacity in TOR is required to cool 2000 cfm of air from 85°F to 70°F? If the specific heat ratio (k) and specific gas constant (R) of air are 1.4 and 0.28708 kJ/kg-K, respectively.

A =Refrigerant vapor rejects 70 kW of heat as it passes through an air-cooled condenser. The condenser has an air-side area of 210 m2 and based on this area, has an overall heat transfer coefficient of 0.037 kW/m?.°C. Cooling air flows at a rate of 7.59 kg/s. If condensation of the refrigerant occurs at 55°C, what is the inlet temperature (in °C) of the air? Take the specific heat of air to be 1.02 kJ/kg.°C. Round your answer to 2 decimal places.(b) Hairdryer is an electromechanical device that blows ambient or hot air over damp hair to speed the evaporation of water to dry the hair. To design a hairdryer, it should contain the following basic components: a duct of constant diameter with a few layers of electric coils, a small fan to pull the air in and force it through the heating coils. If the density of air is 1.18 kg/m³ at the inlet and 0.90 kg/m³ at the exit, calculate the percent increase in the velocity of air as it flows through the dryer.
