Question

A solar heater is installed to heat 1.8 m of water from 20 to 60C. If the average power from the sun hits it with 0.9 kW/m, Estimate the area of the solar heater needed to heat the water in 2 hours if the heat transfer efficiency is about 50% (C for water 4200 J/kg. K).

Step 1

To calculate the energy required to heat the water from 20°C to 60°C, we use the formula: \[ Q = mc\Delta T \] where \( Q \) is the energy required, \( m \) is the mass of the water, \( c \) is the specific heat capacity of water (4200 J/kg.K), and \( \Delta T \) Show more…
