RF Path vs Appliance Cost Calculator Plus

RF Path provides propagation loss calculations for radio frequencies (RF) between 20 MHz and 20 GHz using either the Irregular Terrain model, Okumura-Hata model, COST-231 Hata Extension model, or the COST-231 Walfish-Ikegami model. The calculations are based on both electromagnetic theory and the statistical analysis of terrain characteristics to calculate the degradation of the RF wave as a function of distance and the variability of the RF wave with respect to time and space. The Irregular Terrain Model has two different prediction models. One is the Area Prediction mode which calculates propagation losses over an area where the exact terrain parameters are not known, but approximated using terrain roughness, environmental parameters and statistical parameters. The second is a point-to-point mode where specific latitude/longitude pair values are entered for both transmitter and receiver. Environmental parameters and statistical parameters are also used in this prediction mode. The results may be saved to iCloud, emailed, or posted to Facebook or Twitter. The results are in CSV format. In the Area Prediction mode a table along with a graph shows the path loss over the distance entered into the settings. The graph is viewed by rotating the device once the results table is shown. In the Point-To-Point Prediction mode a table along with a graph shows the path loss and elevation profile of the RF path.

Determine the Cost of Using Appliances in Your Home. Use this calculator to find out the cost of using most major electric appliances. Simply enter the amount of electricity the appliance uses (in watts) and the length of time it is used (in hours), and instantly see the cost and energy consumption. Features: - User-friendly interface. - Add multiple appliances with custom settings. - More than 30 appliance templates ready for fast calculation. - Easily highlight which appliance costs the most. - Instant calculations with results including monthly cost, yearly cost, monthly kWh, and yearly kWh. - Lightweight app with a small size, optimized for everyday use. The Formula: - Electricity Usage Per Month = (Watts / 1000) * Hours/Day * 30 Days = kWh/month - Electricity Usage Per Year = (Watts / 1000) * Hours/Day * 365 Days = kWh/year - Electricity Cost Per Month = (cents/kWh / 100) * 30 Days = $/month - Electricity Cost Per Year = (cents/kWh / 100) * 365 Days = $/year Tips When Calculating Appliance Running Costs: Appliances such as lights, heaters, pumps, motors, and fans that draw constant power are ideal for use with this appliance cost calculator. Some appliances can be switched on 24/7 but only draw power for part of that time. For example, a refrigerator's compressor may only draw power for 8 to 12 hours per day. For these appliances, you can either estimate based on observations or use a power meter. For other appliances, power usage can vary significantly. For example, a dishwasher may use 2400W when heating, 50W when pumping water, and 5W in standby. Estimating an 'average power' for these appliances can be tricky. Any appliance that goes through a 'cycle' like this is best measured with a power meter. Note: For monthly cost calculations, the average number of days used is 30. Results should be used as an indication only and may vary based on the age of the appliance, the latest technology, and other factors. The overall cost of using each appliance in this calculator is approximate and does not include standby power. For example: - Energy use for air-conditioners and heaters depends on thermostat settings and the thermal performance of the room or house. - Energy use for dishwashers and washing machines depends on the wash cycle chosen (i.e., how long it runs) and whether your machine is connected to the hot water tap. 11 Energy-Saving Tips: 1. Use natural light and turn off unnecessary lights. A single south-facing window can illuminate 20 to 100 times its area. 2. Promote airflow through your home and block the afternoon sun during the summer. 3. Unplug unused electronics. Standby power can account for 10% of an average household's annual electricity use. 4. Any appliance that generates heat or cold consumes a lot of energy; use them wisely. 5. Manage your thermostat. If you have electric heat, lower your thermostat by two degrees to save 5% on your heating bill. Lowering it by five degrees could save 10%. 6. For air conditioners, set the temperature to 27°C instead of 17°C. Combined with a fan, you can achieve the desired result. 7. Wash only when there is a full load, and hang-dry your laundry/dishes. 8. Buy and use energy-efficient appliances, such as LED lights and energy-efficient cooking appliances. 9. Insulate your home to help stay warm in winter and cool in summer. 10. Adjust your day-to-day behaviors. 11. Consider making your house an energy-saving smart home. This appliance cost calculator estimates the cost and energy usage of any appliance. Calculate the cost/electricity consumption for an appliance or compare it with new appliances to be purchased.
