How do you find the density of plasticine?

How do you find the density of plasticine?

The equation will now be of the form M = Dd3 where D = πρ/6. Use your value of D to calculate the density of the plasticine, ρ.

What is the density of plasticine?

1.34 g/cm3
The density of plasticine was calculated to be 1.34 g/cm3 with an 8% percentage error associated with it.

What is the transformer formula?

Vp=−NpΔΦΔt V p = − N p Δ Φ Δ t . This is known as the transformer equation, and it simply states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.

How do you find the density of two objects?

Density is the mass per unit volume. It can be measured in several ways. The most accurate way to calculate the density of any solid, liquid or gas is to divide its mass in kilograms by its volume (length × width × height) in cubic metres. The unit for density is kg/m 3.

How do you calculate density?

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

Is plasticine dense?

Plasticine-like materials are appealing to animators because the material can be used with ease: it is mouldable enough to create a character, flexible enough to allow that character to move in many ways, and dense enough to retain its shape easily when combined with a wire armature, and does not melt under hot studio …

How do you calculate the efficiency of a transformer?

Just like any other electrical machine, efficiency of a transformer can be defined as the output power divided by the input power. That is efficiency = output / input . Transformers are the most highly efficient electrical devices. Most of the transformers have full load efficiency between 95% to 98.5% .

How do you calculate flux density of a transformer core?

In a single phase transformer design, the flux density of Core depends upon Voltage applied or Current drawn from it (Ampere Turns)? Flux Density, B=1/(4.44*f*A*Te), where f is the frequency, A is the cross-sectional area of the core, Te is the turn/volt value.

Why is the transformer rated in kVA?

The copper and iron are the two types of losses that occur in the transformer. The copper loss depends on the current (ampere) flows through the windings of the transformer while the iron loss depends on the voltage (volts). i.e., the rating of the transformer is in kVA.

What is the kVA rating of a transformer?

Kilovolt-Ampere
kVA stands for Kilovolt-Ampere and is the rating normally used to rate a transformer. The size of a transformer is determined by the kVA of the load. In many circumstances the power required by the load is equivalent to the rating of the transformer expressed in either VA or kVA.

How do you calculate density formula?

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre.

¿Cuál es el método de cálculo de un transformador?

Tutorial que muestra el método de cálculo de un transformador que hay que seguir para hacer el bobinado cuando se tiene el núcleo y se conocen los voltajes para el primario y el secundario. Fórmula: Área = A X B = 4 cm x 5 cm = 20 cm². Fórmula: Espiras x voltios = K / Área (Espira significa una vuelta en el carretón.)

¿Qué es un transformador reductor?

1-Transformador reductor: Este reduce el voltaje de salida respecto de un voltaje de entrada. En una relación voltios-espiras mediante cálculo.

¿Cuál es el transformador ideal?

El transformador ideal rendirá un 100 % pero en la práctica no existe. Son las chapas de material ferro-magnético, hierro al que se añade una pequeña porción de silicio.

¿Cuál es el rendimiento del transformador?

De su calidad depende que aumente el rendimiento del transformador hasta un valor cercano al 100 %. N1/N2 = V1/V2 léase: número de vueltas del primario sobre el número de vueltas del secundario es igual a la relación entre el voltaje del primario sobre el voltaje del secundario.
