What is the conductance of a 10 ohm's resistor?
Conductance is the reciprocal of resistance, and is measured in siemens (S). So a 5.1 ohm resistor has 1/5.1 conductance, which is approximately 0.196 078 431 372 549 019 607 843 137 254 9 S.
You know 0.02 BTU is needed to raise 1 cu ft of air 1 degree Fahrenheit But how long does it take?
Thanks for the answer. I need to rephrase my question. I have a source of energy, creating heat at the rate of 6000BTU/hour in a room. What to know how long does it take the room temprature changes from 86F to 96FNew Answer:You have the heat input rate (6000 BTU/hr) and you know the size of the room. I don't know this last fact, so the answer will be "plug in your values". Also I assume heat can be distributed very quicklyVolume of Room: HxWxLVolume of air in room = Volume of room - Volume of furniture (assume 800 ft3)Hourly heating rate in ideal conditions =0.02 BTU/hr x 1 ft3 = 1o F/hr0.02 BTU/hr x 800 ft3 = (1/800)o F/hr1 BTU/hr x 800 ft3 = (50/800)o F/hr = 0.062o F/hr6000 BTU/hr x 800 ft3 = (6000 x 0.062)o F/hr = 372o F/hrAssume heating rate is proportional to how long the heater is on (actually a bit off because air is cooled by walls and furniture etc.)For a 800 ft3 room the heater would heat the room 10o F in (10/372) hrs, about (1.5 minutes. For larger or smaller rooms the time would be(1.5 minutes) x 800/(Actual room volume) = Time to raise temperature by 10o F--------------- Rate of temperature change is dependent on how rapidly the energy is supplies. Consder to 1 ft3 boxes of air, insulated so that no heat can enter or leave.In the first box we introduce a small amount of gaseous explosive that will release 0.02 BTU of heat when ignited. In the second a finely divided iron powder that floats in the air and slowly rusts releasing the same amount of energy. The explosion and rusting are allowed to happen. Both boxes now contain air 1o F warmer than the initial condition. One box acheived the change almost instantaneously, the other over the course of hours or days.In real life situations the heat is transferred through the box by convection and conduction. The rate depends on the temperature of the heater and the amount of agitation of the air.
Code for scientific calculator in visual basic?
Prep work: add 3 textboxes and 4 buttons Button1 = Add Button2 = Subtract Button3 = Multiply Button4 = Divide Make sure to keep a textbox for the answer (I'll use one called, "TextBox3") For Button 1: TextBox3.Text = Val(TextBox1.Text) + Val(TextBox2.text) 'This takes text1's value and adds text2's value to it For Button 2: TextBox3.Text = Val(TextBox1.Text) - Val(TextBox2.Text) 'same as button one but subtract For Button 3: TextBox3.Text = Val(TextBox1.Text) * Val(TextBox2.Text) For Button 4: TextBox3.Text = Val(TextBox1.Text) / Val(TextBox2.Text)
Which country code is 371 810?
Country code +372 is Estonia, and +372 81 is a mobile.
Where is telephone country code 372?
Estonia uses country code +372(dialed as 00 372 from many places).(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
