# What is the formula for heat?

Heat=Mass x Specific Heat x Change in Temperature or H=M x Sp. Ht. x ^T

# Formula of heat?

The formula for heat is changing based on a few different factors.For example some materials create heat because they are mixed whileothers must be burned to produce heat.

# Head loss in a pipe?

when a pump is used to pump a fluid into a vertically arranged pipe , fixed upright; the fluid would reach a certain height at which point the fluid would stop in a pipe. …this height at which the fluid has stopped propelling upward could be described as the head of water. this measure relates to the pump power . should a pipe system be used which is less than the head height then fluid will be seen to flow out and over the side of pipe. if the connecting pipe happens to be of longer measurement than the head, and hence when fixed at height is taller than the head height then the fluid will not likely be seen flowing out of pipe . if a pump is mounted within a basement of work hall, but the resulting pressure is utilised on the ground floor of same building then some pressure will be lost when pumping upwards , and could be described as head loss.

# What is heat gain and heat loss?

heat gain is when an object get hotter. heat loss is when an object gets colder.

# What is the formula to find pressure loss in fire fighting pipe lines?

The British fire and rescue services use the following formula for calculating the pressure loss due to friction in firefighting hose:.
P f = 9000 f l L 2 / d 5 bar.
wher…e.
P f is the frictional loss of pressure, in bar f is the friction factor f = 0.005 for 70 mm or 45 mm hose f = 0.007 for 90 mm hose (for 90 mm hose it is higher to allow for losses in the couplings, which are but 64 mm diameter) l is the length of the hose line, in metres L is the flow rate, in litres/minute d is the hose diameter, in millimetres.
The formula is approximate, and relates to internally lined hose in 25 metre lengths. You will find the formula in the old Manual of Firemanship, Book 7, Hydraulics, pumps and pump operation..

# Heat loss in copper pipes?

The thickness of the pipe will effect the loss rate. Best thing to do is buy thermal isulating foam, normally comes in tubes will a slit down one side so it can be slid over… the pipe easily. Also depending on the the fluid inside the conduit ( pipe ) and diameter, ambient temp, and location, you may be able to use a product such as heat trace. It is an electrical wrap that uses voltage and amperage to create heat to shield from the outer elements...

# What are the types of pipe losses?

friction loss head loss loss due to sudden enlargement

# Formula for measuring heat loss or heat gain?

Do a Google search on: ACCA Manual J

# What is pipe friction loss?

The energy lost through friction as a fluid flows through a pipe. The amount of energy lost is dependent on both the characteristics of the fluid (viscosity, density) and the… pipe (roughness, diameter, length) as well as the rate of flow.

# Why heat gained and heat loss?

Since heat flows from high temperature region to low temperature region so when a hotter body comes in contect with colder body then hotter body loses heat to colder body unti…l both have same temperature.

# What is heat loss formulae of water flow through PPR-C pipe line?

you have first to know the thermal conductivity of PPR that you are dealing with. normally, this is in range between 0.1 to 0.24 W/MK .then you apply this formula Q(IN WATTS) …=Thermal Conductivity/MK)*A( surface area for the pipe M2 )temperature difference between fluid inside pipe and temprture of pipe surface K)/(thickness of the pipe M)

# What is a heat no on pipe?

Used for inspection. Heat numbers make it possible to trace pipe from spools fabricated on a job to material documentation from a given melt. The matching documents will tell …when and where the pipe was made, the material used and the pipe grade etc.
