On a hot day, the temperature of a 33,000 L swimming pool increases by 1.70°C. What is the net heat transfer (in J) during this heating? Ignore any complications, such as loss of water by evaporation. (Enter the magnitude.)
A swimming pool (dimensions: 50m x 2m50 x 16m) has a temperature of 20.00°C. Due to the evaporation of the surface water, this pool loses approximately 910.0 kJ/m2.h. To compensate for this loss, the water is heated by burning methane (CH4). Methane has a pressure of exactly 4 atm and a temperature of 20.00°C. What volume of methane should be burned? Answer [4911 l/h]
On a certain dry sunny day, a swimming pool’s temperature would rise by 2.465ºC if not for evaporation. What percent of the water must evaporate to carry away precisely enough energy to keep the temperature constant? Specific heat of water is 1.00 kcal/kgºC and the heat of vaporization is 580 kcal/kg.
Task 4 It is proposed that the shower facility at a new swimming pool will recover heat from flue of the central boiler to provide a small supply of hot water for the showers using a water-gas heat exchanger. The required water temperature is approximately 38 °C and the flow rate of water per shower is 15 litres per minute. Up to 20 showers will be in use at any one time. If water enters the facility at 15 °C...

The following data was recorded for the hot water cylinder and heating system during a period of constant load: thermal capacitance of hot water cylinder.. .150 ki/C heat input (thermostat on.... heat loss (load ahd insulation losses)... 500 W desired operating temperature . dead band (neutral zon1-2°C For this period, determine: (a) The amplitude of...
system, hot water at an average temperature of 80°C is flowing through a 15-m section of a cast In a heating iron pipe (k 50 W/m K) whose inner and outer diameters are 4 cm and 5 cm, respectively. The outer surface of the pipe, whose emissivity is 0.75, is exposed to the cold air at 10°C in the basement. with a heat transfer coefficient of 15 W/m2.K. The heat transfer coefficient at the inner surface of the pipe is...
On a summer day, the air temperature is 36°C and the relative humidity is 20%. Water evaporates from the surface of a lake at a rate of 0.20 kg/h per square metre of water surface area. The temperature of water is 25°C. (a) Determine the mass transfer coefficient. (10 marks) (b) Determine the convective heat transfer coefficient. (10 marks) (c) Determine the net heat loss (in W/m2) from the lake. (5 marks) The specific volume of water vapour at 25°C...
You heat 1 L of water and its temperature increases to 10 ° C. if the same heat is applied with 2 L of water. How much did the temperature rise? to 3 L of water? Write your response next to the blank spaces below. 1L = 10°C 2L = 3L = 2. a Big bucket contains 1 L of water at 20 ° C. What will be the temperature of the mix when 1 L of water at 20...
HoMEWORK FOR INTRODUCTION TO HEAT AND TEMPERATURE 1. Approximately what is human body temperature on the Celsius temperature scale? Which is better at transferring heat, water or air? How does this fact explain the length of time it takes the temperature probe to reach thermal equilibrium with the air or water it is in? 2. 3. What effect does the evaporation of water have on the object from which it is evaporating? When has your body experienced this effect? 4....
